1 · What the graph read from it

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.

2 · The registry

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

backgroundHydroxymethylglutaryl-coenzyme A reductase inhibitors (statins) are antihyperlipidemic drugs with an established efficacy in stabilizing atherosclerotic plaques and preventing atherogenesis and reducing cardiovascular events. The purpose of this study was to determine the effect of simvastatin on serum Vitamin D status in dyslipidemic patients as Vitamin D status has an impact on monocyte/macrophage function and may also contribute to cardiovascular risk.

methodsSelected individuals (n = 102) were treated with simvastatin (40 mg/day), or matching placebo in a randomized, double-blind, placebo-controlled, crossover trial. Each treatment period (with simvastatin or placebo) lasted for 30 days and was separated by a 2-week washout phase. Serum Vitamin D concentration was assessed pre- and post-treatment.

resultsSeventy-seven completed the trial, noncompliance with the study protocol and drug intolerance or relocation were the causes for drop-out. No significant carry-over effect was observed for the assessed parameters. There was a reduction in the serum levels of low-density lipoprotein cholesterol (P < 0.001), total cholesterol (P < 0.001), and triglycerides (P < 0.05). Nevertheless, simvastatin therapy did not significantly affect serum level of high-density lipoprotein cholesterol and Vitamin D level (P > 0.05).

conclusionsShort-term treatment with simvastatin (40 mg/day) does not have a significant affect on serum levels of Vitamin D.
