Meta-Analysis
Previous studies showed that statins reduce the progression of kidney function decline and proteinuria, but whether specific types of statins are more beneficial than others remains unclear. We performed a network meta-analysis of randomized controlled trials (RCT) to investigate which statin most effectively reduces kidney function decline and proteinuria. We searched MEDLINE, Embase, Web of Science, and the Cochrane database until July 13, 2018, and included 43 RCTs (>110,000 patients). We performed a pairwise random-effects meta-analysis and a network meta-analysis according to a frequentist approach. We assessed network inconsistency, publication bias, and estimated for each statin the probability of being the best treatment. Considerable heterogeneity was present among the included studies. In pairwise meta-analyses, 1-year use of statins versus control reduced kidney function decline by 0.61 (95%-CI: 0.27; 0.95) mL/min/1.73 m and proteinuria with a standardized mean difference of -0.58 (95%-CI:-0.88; -0.29). The network meta-analysis for the separate endpoints showed broad confidence intervals due to the small number available RCTs for each individual comparison. In conclusion, 1-year statin use versus control attenuated the progression of kidney function decline and proteinuria. Due to the imprecision of individual comparisons, results were inconclusive as to which statin performs best with regard to renal outcome.

OBJECTIVE
The aim of this study was to examine and present the effect of statin treatment on the low-density lipoprotein (LDL) cholesterol level of patients in Turkey by evaluating the data of studies conducted in the country.
METHODS
Manuscripts published between January 1, 2008 and December 31, 2017 with terms 'LDL' and 'TURK' in the title or abstract and reporting LDL cholesterol data of patients treated with statins were evaluated for inclusion in the study. From the initial search result a total of 1795 papers, 39 manuscripts with 63 study arms were selected for analysis and the data of 3486 patients were included. Descriptive analysis was used to assess the data. Weighted averages of the data were also calculated.
RESULTS
The female/male ratio was 42/58. The mean age was 52.9±10.1 years. The proportion of patients with the recommended LDL cholesterol level of <70 mg/dL after treatment with statins was 15.3%;. In all, 10.2% of the patients who were prescribed a low-dose statin and 28.0% of those who were prescribed a high-dose statin had an LDL cholesterol of <70 mg/dL after treatment. Among patients who were being treated with statins for ≤2 months, 25.7% achieved an LDL cholesterol level of <70 mg/dL. Among those who were being treated with statins for 2-4 months and >4 months the proportion was 11.4% and 9.7%, respectively. The percentage of patients at the target level was 21.8%, 21.7%, 17.9%;, 8.6%, and 0.8% among those using atorvastatin, simvastatin, rosuvastatin, fluvastatin, and pravastatin, respectively.
CONCLUSION
In Turkey, only 15% of the patients who had received statin therapy had a LDL cholesterol level of <70 mg/dL. Revision of the current treatment should be considered to reach the target levels recommended in the guidelines, especially for patients with high cardiovascular risk.
