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

purposeTo investigate the blood pressure (BP)-lowering effects of statins by conducting a systematic review and meta-analysis of placebo-randomized controlled trials (RCTs).

methodWe conducted a meta-analysis of placebo RCTs reporting antihypertensive effects of statins therapy. We only included RCTs that did not allow for concomitant antihypertensive therapy, or clearly stated that antihypertensive therapy was fixed throughout the study period.

resultsOur meta-analysis included 46 placebo RCTs, including 53 group comparisons and a total of 49,087 participants (24,589 participants in the statin groups and 24,498 participants in the placebo group). Subgroup analysis, based on use of concomitant antihypertensive, was performed. The meta-analysis showed that statin reduced systolic BP by - 1.6 mmHg (95% CI: - 2.50 to - 0.60), and diastolic BP by - 0.96 mmHg (95% CI: - 1.36 to - 0.56). Although the presence of concomitant antihypertensive therapy diluted the BP lowering effect of statins, it remained statistically significant and independent of the lipid-lowering activity. Furthermore, the BP -lowering effect of the statins was independent of the dose or type of statin (p > 0.05).

conclusionOur results strengthen the evidence for pleiotropic effects of statins on BP that are independent of their lipid-lowering activity, supporting their beneficial role in hypertensive patients with dyslipidemia.
