Efficacy and safety of pitavastatin versus simvastatin: a meta-analysis of randomized controlled trials.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesPitavastatin is the latest statin to be approved and has shown beneficial effects on plasma lipid profiles. The aim of the present meta-analysis was to assess both the efficacy and safety of pitavastatin versus simvastatin, one of the most commonly used statins.
methodsA search of the MEDLINE, EMBASE, OVID and Cochrane Central Register of Controlled Trials (CENTRAL) databases was undertaken. Clinical trials evaluating the efficacy and safety of simvastatin versus pitavastatin, published up to February 2014, were identified. Trials were included if they (1) were randomized controlled trials (RCTs) of at least 12 weeks' duration; (2) included patients with primary hypercholesterolaemia or mixed dyslipidaemia; (3) studied outcomes included low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C); and (4) were published in the English language. A fixed-effects model was used for data analysis if no significant heterogeneity was present; otherwise a random-effects model was used. Efficacy is reflected by the mean difference in the percentage change of plasma lipid profiles. Treatment-emergent adverse events (TEAEs) are presented as risk ratio (RR).
resultsA total of 1,468 patients were included in the meta-analysis. The results indicated similar efficacy of pitavastatin (versus simvastatin) in lowering LDL-C. Pitavastatin also had similar effects to simvastatin on other major aspects of plasma lipids, including TC, TG and HDL-C. Somewhat in contrast to common belief (based on distinct metabolism by P450 subtypes), the two statins did not differ in the incidence of TEAE.
conclusionsIn clinical trials, pitavastatin was comparable to simvastatin in both efficacy and safety profile. Large-scale, high-quality observational studies are required to determine whether the advantage of pitavastatin in metabolism profiles could be translated into noticeable benefits.
