BJU International Jun 2015To systematically review and create nomograms of flaccid and erect penile size measurements. (Review)
Review
OBJECTIVE
To systematically review and create nomograms of flaccid and erect penile size measurements.
METHODS
Study key eligibility criteria: measurement of penis size by a health professional using a standard procedure; a minimum of 50 participants per sample.
EXCLUSION CRITERIA
samples with a congenital or acquired penile abnormality, previous surgery, complaint of small penis size or erectile dysfunction. Synthesis methods: calculation of a weighted mean and pooled standard deviation (SD) and simulation of 20,000 observations from the normal distribution to generate nomograms of penis size.
RESULTS
Nomograms for flaccid pendulous [n = 10,704, mean (SD) 9.16 (1.57) cm] and stretched length [n = 14,160, mean (SD) 13.24 (1.89) cm], erect length [n = 692, mean (SD) 13.12 (1.66) cm], flaccid circumference [n = 9407, mean (SD) 9.31 (0.90) cm], and erect circumference [n = 381, mean (SD) 11.66 (1.10) cm] were constructed. Consistent and strongest significant correlation was between flaccid stretched or erect length and height, which ranged from r = 0.2 to 0.6.
LIMITATIONS
relatively few erect measurements were conducted in a clinical setting and the greatest variability between studies was seen with flaccid stretched length.
CONCLUSIONS
Penis size nomograms may be useful in clinical and therapeutic settings to counsel men and for academic research.

Journal of Dentistry Nov 2022To systematically retrieve and assess studies regarding the effectiveness of basic behavioral management techniques (BMTs) in pediatric patients. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To systematically retrieve and assess studies regarding the effectiveness of basic behavioral management techniques (BMTs) in pediatric patients.
DATA SOURCES
Electronic and hand searches were conducted to locate Randomized Controlled Trials (RCTs) reporting on objective and subjective evaluation of anxiety and behavior of children up to 12 years of age. Data extraction and risk of bias evaluation, using the Cochrane risk of bias tool (RoB 2.0 Tool), were performed independently and in duplicate for all included studies. Mean differences and standard deviations were used to summarize the data from each study and meta-analyses were conducted with studies of limited heterogeneity.
STUDY SELECTION
A total of 708 papers were identified and screened, 122 retrieved for full text appraisal and 62 finally included. Results suggested that all basic BMTs have acceptable effectiveness on pediatric patients' anxiety, fear and behavior during dental treatment. Meta-analysis showed a statistically significant difference in favor of distraction for subjective anxiety using Facial scale (Mean diff.: 2.78; 95% CI: -3.08, -0.53; p = 0.005) and Modified Child Dental Anxiety Scale (Mean diff.: 12.76; 95% CI: -6.09, -4.47; p = 0.001) and a non-significant difference for heart rate (Mean diff.: 1.70; 95% CI: -6.54, 0.46; p = 0.09). Music significantly reduced heart rate when compared to a control comparator, underlining the superiority of the BMT (Mean diff.: 2.71; 95% CI: -3.70, -0.59; p = 0.007).
CONCLUSIONS
Limited evidence about efficacy of one technique over another raises important issues on the topic for future research regarding the management of the child patient in the dental setting of the 21st century.
CLINICAL SIGNIFICANCE
Behavioral management comprises a challenge for clinicians, who need to be familiar with a range of techniques to meet patients' needs at individual level and be flexible in their implementation. Appropriate technique should incorporate patients' personality and parents' active involvement, within the contents of the changes in modern societies.

Patients With Knee Osteoarthritis Who Receive Platelet-Rich Plasma or Bone Marrow Aspirate Concentrate Injections Have Better Outcomes Than Patients Who Receive Hyaluronic Acid: Systematic Review and Meta-analysis.
PURPOSE
To systematically review the literature to compare the efficacy and safety of platelet-rich plasma (PRP), bone marrow aspirate concentrate (BMAC), and hyaluronic acid (HA) injections for the treatment of knee osteoarthritis (OA).
METHODS
A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to identify Level I studies that compared the clinical efficacy of at least 2 of the following 3 injection therapies: PRP, BMAC, and HA for knee OA. The search phrase used was knee AND osteoarthritis AND randomized AND ("platelet rich plasma" OR "bone marrow aspirate" OR "hyaluronic acid"). Patients were primarily assessed based on patient-reported outcome scores (PROs) including the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, and Subjective International Knee Documentation Committee (IKDC) score.
RESULTS
Twenty-seven studies (all Level I) met inclusion criteria, including 1,042 patients undergoing intra-articular injection(s) with PRP (mean age 57.7 years, mean follow-up 13.5 months), 226 patients with BMAC (mean age 57.0 years, mean follow-up 17.5 months), and 1,128 patients with HA (mean age 59.0 years, mean follow-up 14.4 months). Nonnetwork meta-analyses demonstrated significantly better postinjection WOMAC (P < .001), VAS (P < .01), and Subjective IKDC scores (P < .001) in patients who received PRP compared with patients who received HA. Similarly, network meta-analyses demonstrated significantly better postinjection WOMAC (P < .001), VAS (P = .03), and Subjective IKDC (P < .001) scores in patients who received BMAC compared with patients who received HA. There were no significant differences in postinjection outcome scores when comparing PRP with BMAC.
CONCLUSIONS
Patients undergoing treatment for knee OA with PRP or BMAC can be expected to experience improved clinical outcomes when compared with patients who receive HA.

Meta-Analysis Review
BACKGROUND
The effects of balance training (BT) in older adults on proxies of postural control and mobility are well documented in the literature. However, evidence-based dose-response relationships in BT modalities (i.e., training period, training frequency, training volume) have not yet been established in healthy older adults.
OBJECTIVES
The objectives of this systematic literature review and meta-analysis are to quantify BT intervention effects and to additionally characterize dose-response relationships of BT modalities (e.g., training period, training frequency) through the analysis of randomized controlled trials (RCTs) that could maximize improvements in balance performance in healthy community-dwelling older adults.
DATA SOURCES
A computerized systematic literature search was performed in the electronic databases PubMed and Web of Science from January 1985 up to January 2015 to capture all articles related to BT in healthy old community-dwelling adults.
STUDY ELIGIBILITY CRITERIA
A systematic approach was used to evaluate the 345 articles identified for initial review. Only RCTs were included if they investigated BT in healthy community-dwelling adults aged ≥65 years and tested at least one behavioral balance performance outcome (e.g., center of pressure displacements during single-leg stance). In total, 23 studies met the inclusionary criteria for review.
STUDY APPRAISAL AND SYNTHESIS METHODS
Weighted mean standardized mean differences between subjects (SMDbs) of the intervention-induced adaptations in balance performance were calculated using a random-effects model and tested for an overall intervention effect relative to passive controls. The included studies were coded for the following criteria: training modalities (i.e., training period, training frequency, training volume) and balance outcomes [static/dynamic steady-state (i.e., maintaining a steady position during standing and walking), proactive balance (i.e., anticipation of a predicted perturbation), reactive balance (i.e., compensation of an unpredicted perturbation) as well as balance test batteries (i.e., combined testing of different balance components as for example the Berg Balance Scale)]. Heterogeneity between studies was assessed using I2 and Chi2-statistics. The methodological quality of each study was tested by means of the Physiotherapy Evidence Database (PEDro) Scale.
RESULTS
Weighted mean SMDbs showed that BT is an effective means to improve static steady-state (mean SMDbs = 0.51), dynamic steady-state (mean SMDbs = 0.44), proactive (mean SMDbs = 1.73), and reactive balance (mean SMDbs = 1.01) as well as the performance in balance test batteries (mean SMDbs = 1.52) in healthy older adults. Our analyses regarding dose-response relationships in BT revealed that a training period of 11-12 weeks (mean SMDbs= 1.26), a frequency of three training sessions per week (mean SMDbs= 1.20), a total number of 36-40 training sessions (mean SMDbs = 1.39), a duration of a single training session of 31-45 min (mean SMDbs = 1.19), and a total duration of 91-120 min of BT per week (mean SMDbs = 1.93) of the applied training modalities is most effective in improving overall balance performance. However, it has to be noted that effect sizes for the respective training modalities were computed independently (i.e., modality specific). Because of the small number of studies that reported detailed information on training volume (i.e., number of exercises per training session, number of sets and/or repetitions per exercise, duration of single-balance exercises) dose-response relationships were not computed for these parameters.
LIMITATIONS
The present findings have to be interpreted with caution because we indirectly compared dose-response relationships across studies using SMDbs and not in a single controlled study as it is difficult to separate the impact of a single training modality (e.g., training frequency) from that of the others. Moreover, the quality of the included studies was rather limited with a mean PEDro score of 5 and the heterogeneity between studies was considerable (i.e., I2 = 76-92 %).
CONCLUSIONS
Our detailed analyses revealed that BT is an effective means to improve proxies of static/dynamic steady-state, proactive, and reactive balance as well as performance in balance test batteries in healthy older adults. Furthermore, we were able to establish effective BT modalities to improve balance performance in healthy older adults. Thus, practitioners and therapists are advised to consult the identified dose-response relationships of this systematic literature review and meta-analysis. However, further research of high methodologic quality is needed to determine (1) dose-response relationships of BT in terms of detailed information on training volume (e.g., number of exercises per training session) and (2) a feasible and effective method to regulate training intensity in BT.

Meta-Analysis Review
CONTEXT
Current perception dictates that glenohumeral internal rotation deficit (GIRD) is a chronic adaptation that leads to an increased risk of pathologic conditions in the dominant shoulder or elbow of overhead athletes.
OBJECTIVE
To determine whether adaptations in glenohumeral range of motion in overhead athletes lead to injuries of the upper extremity, specifically in the shoulder or elbow.
DATA SOURCES
An electronic database search was performed using Medline, Embase, and SportDiscus from 1950 to 2016. The following keywords were used: GIRD, glenohumeral internal rotation deficit, glenohumeral deficit, shoulder, sport, injury, shoulder joint, baseball, football, racquet sports, volleyball, javelin, cricket, athletic injuries, handball, lacrosse, water polo, hammer throw, and throwing injury.
STUDY SELECTION
Seventeen studies met the inclusion criteria for this systematic review. Of those 17 studies, 10 included specific range of motion measurements required for inclusion in the meta-analysis.
STUDY DESIGN
Systematic review and meta-analysis.
LEVEL OF EVIDENCE
Level 4.
DATA EXTRACTION
Data on demographics and methodology as well as shoulder range of motion in various planes were collected when possible. The primary outcome of interest was upper extremity injury, specifically shoulder or elbow injury.
RESULTS
The systematic review included 2195 athletes (1889 males, 306 females) with a mean age of 20.8 years. Shoulders with GIRD favored an upper extremity injury, with a mean difference of 3.11° (95% CI, -0.13° to 6.36°; P = 0.06). Shoulder total range of motion suggested increased motion (mean difference, 2.97°) correlated with no injury ( P = 0.11), and less total motion (mean difference, 1.95°) favored injury ( P = 0.14). External rotational gain also favored injury, with a mean difference of 1.93° ( P = 0.07).
CONCLUSION
The pooled results of this systematic review and meta-analysis did not reach statistical significance for any shoulder motion measurement and its correlation to shoulder or elbow injury. Results, though not reaching significance, favored injury in overhead athletes with GIRD, as well as rotational loss and external rotational gain.

Meta-Analysis
BACKGROUND
The benefits and risks of testosterone treatment for women with diminished sexual wellbeing remain controversial. We did a systematic review and meta-analysis to assess potential benefits and risks of testosterone for women.
METHODS
We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and Web of Science for blinded, randomised controlled trials of testosterone treatment of at least 12 weeks' duration completed between Jan 1, 1990, and Dec 10, 2018. We also searched drug registration applications to the European Medicine Agency and the US Food and Drug Administration to identify any unpublished data. Primary outcomes were the effects of testosterone on sexual function, cardiometabolic variables, cognitive measures, and musculoskeletal health. This study is registered with the International Prospective Register of Systematic Reviews (PROSPERO), number CRD42018104073.
FINDINGS
Our search strategy retrieved 46 reports of 36 randomised controlled trials comprising 8480 participants. Our meta-analysis showed that, compared with placebo or a comparator (eg, oestrogen, with or without progestogen), testosterone significantly increased sexual function, including satisfactory sexual event frequency (mean difference 0·85, 95% CI 0·52 to 1·18), sexual desire (standardised mean difference 0·36, 95% CI 0·22 to 0·50), pleasure (mean difference 6·86, 95% CI 5·19 to 8·52), arousal (standardised mean difference 0·28, 95% CI 0·21 to 0·35), orgasm (standardised mean difference 0·25, 95% CI 0·18 to 0·32), responsiveness (standardised mean difference 0·28, 95% CI 0·21 to 0·35), and self-image (mean difference 5·64, 95% CI 4·03 to 7·26), and reduced sexual concerns (mean difference 8·99, 95% CI 6·90 to 11·08) and distress (standardised mean difference -0·27, 95% CI -0·36 to -0·17) in postmenopausal women. A significant rise in the amount of LDL-cholesterol, and reductions in the amounts of total cholesterol, HDL-cholesterol, and triglycerides, were seen with testosterone administered orally, but not when administered non-orally (eg, by transdermal patch or cream). An overall increase in weight was recorded with testosterone treatment. No effects of testosterone were reported for body composition, musculoskeletal variables, or cognitive measures, although the number of women who contributed data for these outcomes was small. Testosterone was associated with a significantly greater likelihood of reporting acne and hair growth, but no serious adverse events were recorded.
INTERPRETATION
Testosterone is effective for postmenopausal women with low sexual desire causing distress, with administration via non-oral routes (eg, transdermal application) preferred because of a neutral lipid profile. The effects of testosterone on individual wellbeing and musculoskeletal and cognitive health, as well as long-term safety, warrant further investigation.

Meta-Analysis
OBJECTIVE
Currently, pharmaceutical treatment options for autism spectrum disorder are limited. Brain glutaminergic dysregulation is observed in autism spectrum disorder. -acetylcysteine, which can be converted to glutathione and subsequently release glutamate into the extracellular space, and thus reduce glutamatergic neurotransmission at synapses, is considered a potential drug for autism spectrum disorder treatment. Here, we analyzed the treatment effects of -acetylcysteine on autism spectrum disorder in randomized controlled trials.
STUDY DESIGN
Updated systematic review and meta-analysis.
DATA SOURCES
By systematically searching the PubMed, Embase and Cochrane Library, we obtained five randomized controlled trials.
STUDY SELECTION
Meta-analyses were performed to examine the improvement in autistic behaviors as measured by the Aberrant Behavior Checklist, Social Responsiveness Scale and Repetitive Behavior Scale-Revised, using mean difference with a 95% confidence interval and a random-effects model.
DATA SYNTHESIS
After 8-12 weeks of -acetylcysteine supplementation, the pooled result of four trials revealed an improvement in Aberrant Behavior Checklist total score (mean difference = 1.31, 95% confidence interval = [0.42, 2.20]). When one trial was excluded, the sensitivity test result was stronger (mean difference = 1.88, 95% confidence interval = [0.92, 2.83]). The pooled results of three trials revealed significant improvements in hyperactivity (mean difference = 4.80, 95% confidence interval = [1.20, 8.40]) and irritability (mean difference = 4.07, 95% confidence interval = [1.13, 7.04]). Regarding Social Responsiveness Scale, the pooled result of two trials showed significant improvement in social awareness after 8-12 weeks of -acetylcysteine supplementation (mean difference = 1.34, 95% confidence interval = [0.09, 2.59]). No differences were observed in the pooled results of two trials using Repetitive Behavior Scale, either in the total or the subscales.
CONCLUSION
We concluded that -acetylcysteine is safe and tolerable, reduces hyperactivity and irritability and enhances social awareness in children with autism spectrum disorder. However, further evidence should be sought before a general recommendation.

Meta-Analysis Review
BACKGROUND
Resistance training (RT) is an intervention frequently used to improve muscle strength and morphology in old age. However, evidence-based, dose-response relationships regarding specific RT variables (e.g., training period, frequency, intensity, volume) are unclear in healthy old adults.
OBJECTIVES
The aims of this systematic review and meta-analysis were to determine the general effects of RT on measures of muscle strength and morphology and to provide dose-response relationships of RT variables through an analysis of randomized controlled trials (RCTs) that could improve muscle strength and morphology in healthy old adults.
DATA SOURCES
A computerized, systematic literature search was performed in the electronic databases PubMed, Web of Science, and The Cochrane Library from January 1984 up to June 2015 to identify all RCTs related to RT in healthy old adults.
STUDY ELIGIBILITY CRITERIA
The initial search identified 506 studies, with a final yield of 25 studies. Only RCTs that examined the effects of RT in adults with a mean age of 65 and older were included. The 25 studies quantified at least one measure of muscle strength or morphology and sufficiently described training variables (e.g., training period, frequency, volume, intensity).
STUDY APPRAISAL AND SYNTHESIS METHODS
We quantified the overall effects of RT on measures of muscle strength and morphology by computing weighted between-subject standardized mean differences (SMDbs) between intervention and control groups. We analyzed the data for the main outcomes of one-repetition maximum (1RM), maximum voluntary contraction under isometric conditions (MVC), and muscle morphology (i.e., cross-sectional area or volume or thickness of muscles) and assessed the methodological study quality by Physiotherapy Evidence Database (PEDro) scale. Heterogeneity between studies was assessed using I2 and χ2 statistics. A random effects meta-regression was calculated to explain the influence of key training variables on the effectiveness of RT in terms of muscle strength and morphology. For meta-regression, training variables were divided into the following subcategories: volume, intensity, and rest. In addition to meta-regression, dose-response relationships were calculated independently for single training variables (e.g., training frequency).
RESULTS
RT improved muscle strength substantially (mean SMDbs = 1.57; 25 studies), but had small effects on measures of muscle morphology (mean SMDbs = 0.42; nine studies). Specifically, RT produced large effects in both 1RM of upper (mean SMDbs = 1.61; 11 studies) and lower (mean SMDbs = 1.76; 19 studies) extremities and a medium effect in MVC of lower (mean SMDbs = 0.76; four studies) extremities. Results of the meta-regression revealed that the variables "training period" (p = 0.04) and "intensity" (p < 0.01) as well as "total time under tension" (p < 0.01) had significant effects on muscle strength, with the largest effect sizes for the longest training periods (mean SMDbs = 2.34; 50-53 weeks), intensities of 70-79% of the 1RM (mean SMDbs = 1.89), and total time under tension of 6.0 s (mean SMDbs = 3.61). A tendency towards significance was found for rest in between sets (p = 0.06), with 60 s showing the largest effect on muscle strength (mean SMDbs = 4.68; two studies). We also determined the independent effects of the remaining training variables on muscle strength. The following independently computed training variables are most effective in improving measures of muscle strength: a training frequency of two sessions per week (mean SMDbs = 2.13), a training volume of two to three sets per exercise (mean SMDbs = 2.99), seven to nine repetitions per set (mean SMDbs = 1.98), and a rest of 4.0 s between repetitions (SMDbs = 3.72). With regard to measures of muscle morphology, the small number of identified studies allowed us to calculate meta-regression for the subcategory training volume only. No single training volume variable significantly predicted RT effects on measures of muscle morphology. Additional training variables were independently computed to detect the largest effect for the single training variable. A training period of 50-53 weeks, a training frequency of three sessions per week, a training volume of two to three sets per exercise, seven to nine repetitions per set, a training intensity from 51 to 69% of the 1RM, a total time under tension of 6.0 s, a rest of 120 s between sets, and a rest of 2.5 s between repetitions turned out to be most effective.
LIMITATIONS
The current results must be interpreted with caution because of the poor overall methodological study quality (mean PEDro score 4.6 points) and the considerable large heterogeneity (I2) = 80%, χ2 = 163.1, df = 32, p < 0.01) for muscle strength. In terms of muscle morphology, our search identified nine studies only, which is why we consider our findings preliminary. While we were able to determine a dose-response relationship based on specific individual training variables with respect to muscle strength and morphology, it was not possible to ascertain any potential interactions between these variables. We recognize the limitation that the results may not represent one general dose-response relationship.
CONCLUSIONS
This systematic literature review and meta-analysis confirmed the effectiveness of RT on specific measures of upper and lower extremity muscle strength and muscle morphology in healthy old adults. In addition, we were able to extract dose-response relationships for key training variables (i.e., volume, intensity, rest), informing clinicians and practitioners to design effective RTs for muscle strength and morphology. Training period, intensity, time under tension, and rest in between sets play an important role in improving muscle strength and morphology and should be implemented in exercise training programs targeting healthy old adults. Still, further research is needed to reveal optimal dose-response relationships following RT in healthy as well as mobility limited and/or frail old adults.

Comparative Study Meta-Analysis Review
INTRODUCTION
A systematic literature review (SLR) and network meta-analysis (NMA) were conducted to evaluate the comparative efficacy of brolucizumab relative to other anti-vascular endothelial growth factor (VEGF) treatments for neovascular age-related macular degeneration (nAMD) at 1 and 2 years, and overall safety and injection frequency of each treatment.
METHODS
An SLR identifying randomized controlled trials (RCTs) published before June 2021 according to a pre-specified protocol was followed by a Bayesian NMA to compare brolucizumab (6 mg q12w/q8w) against sham and all relevant anti-VEGF regimens. Pooled mean injection frequency, serious adverse ocular events, and discontinuation rates were estimated for each treatment regimen.
RESULTS
Nineteen RCTs were included in NMA base-case analysis. Brolucizumab (6 mg q12w/q8w) with loading-phase (LP) demonstrated superior best-corrected visual acuity (BCVA) gains to sham both at year 1 (mean difference 16.8 [95%CrI 13.3, 20.4]) and year 2 (mean difference 21.2 [95%CrI 17.4, 25.0]) and was comparable to other anti-VEGFs. Brolucizumab (6 mg q12w/q8w) also showed superior retinal thickness reduction to most comparators including ranibizumab (0.5 mg q4w; year 1 mean difference - 50.1 [95%CrI - 70.3, - 29.8]; year 2 mean difference - 49.5 [95%CrI - 70.8, - 28.6]), aflibercept (2 mg q8w; year 1 mean difference - 39.7 [95%CrI - 52.9, - 26.4]; year 2 mean difference - 35.0 [95%CrI - 49.1, - 21.4]), and faricimab (6 mg q16w/q8w; year 1 mean difference - 27.6 [95%CrI - 42.3, - 12.8]). Brolucizumab (6 mg q12w/q8w) showed similar rates of treatment discontinuation and serious and overall adverse events (both years). At year 2, pooled annualized injection frequency was lowest for brolucizumab (6 mg q12w/q8w) and highest for ranibizumab (0.5 mg q4w) at 5.7 and 11.5 injections annually, respectively.
CONCLUSION
Among all licensed anti-VEGF treatments, brolucizumab showed superior reduction in retinal thickness and comparable BCVA gains and discontinuation rates, despite having the lowest injection frequency. The current study provides the most up-to-date, robust comparison of treatments for nAMD.

Meta-Analysis Review
BACKGROUND
Heart failure can be classified into chronic heart failure and acute heart failure. Rapid onsets or worsening symptoms characterize acute heart failure, while progressive symptoms characterize chronic heart failure. Exercise-based cardiac rehabilitation is recommended for chronic heart failure patients, yet controversies on whether early exercise is safe and advantageous for acute heart failure patients remain unclear.
OBJECTIVES
We performed a systematic review and meta-analysis to explore the effects of early exercise on cardiac rehabilitation-related outcome in acute heart failure patients.
METHODS
We searched PubMed, Web Of Science, Embase, the Cochrane Library, CINAHL, PsycINFO, China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Database (VIP), Wanfang Dataset and SinoMed Dataset (from the earliest date available to August 2021) for randomized controlled trials that evaluated the effects of early exercise in acute heart failure patients. Studies were selected according to inclusion and exclusion criteria. Data synthesis was performed with Review Manager 5.2.
RESULTS
13 studies met the study criteria, including 1466 patients. Compared to the control group [routine care], early exercise improved 6 min walk distance[mean difference = 33.10, 95% CI (31.43, 34.77), P < 0.001], short physical performance battery scores[mean difference = 1.40, 95% CI (1.36, 1.44), P < 0.001], N-terminal pro-B-type natriuretic peptide[mean difference = -58.84, 95% CI (-89.25, -28.43), P < 0.001], quality of life assessed by Minnesota heart failure quality of life questionnaire [mean difference = -6.55, 95% CI (-9.99, -3.11), P = 0.0002], quality of life assessed by Kansas city cardiomyopathy questionnaire [mean difference = 7.00, 95% CI (6.58, 7.42), P < 0.001], activities of daily living [mean difference = 4.43, 95% CI (2.20, 6.65), P < 0.001], and all-cause related readmission rate [mean difference = 0.69, 95% CI (0.51, 0.94), P = 0.02]. No significant difference in left ventricular ejection fraction [mean difference = 1.93, 95% CI (-2.19, 6.05), P = 0.36], heart failure-related readmission rate [mean difference = 0.76, 95% CI (0.50, 1.17), P = 0.21] and all-cause mortality [mean difference = 0.63, 95% CI (0.18, 2.24), P = 0.47] was found between early exercise group and control group. No adverse events occurred during the intervention.
CONCLUSION
Compared to routine care, early exercise could significantly improve the effect of physical capacity, physiological outcomes and clinical outcomes in acute heart failure patients, and appeared to be safe.
