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

backgroundSeveral real-world observational studies have investigated the association between statin treatment and outcomes of cardioembolic stroke. However, substantial uncertainties remain about this association.

objectiveWe aimed to perform a systematic review and meta-analysis to determine the effect of statin treatment on the outcomes of cardioembolic stroke.

methodsWe systematically searched the PubMed and Embase databases for relevant clinical studies. Pooled relative risks (RRs) and 95% confidence intervals (CIs) with a random-effects model were used to assess the outcomes of interest.

resultsA total of 18 observational studies published between 2009 and 2020 were included. No randomized clinical trial was found. Compared with non-statin treatment, statin treatment was not associated with a decreased risk of stroke recurrence in patients with cardioembolic stroke [PWCS] (RR, 0.93; 95% CI 0.82-1.06). However, compared with non-statin treatment, statin treatment was associated with a lower risk of all-cause death (RR, 0.59; 95% CI 0.49-0.73) and better functional outcomes (RR, 0.67; 95% CI 0.47-0.97) in PWCS. There was no significant association between statin treatment and major bleeding event risk in PWCS (RR, 0.35; 95% CI 0.06-2.16). Compared with non-statin treatment, statin treatment was not associated with a decreased risk of coronary atherosclerotic disease in PWCS (RR, 1.04; 95% CI 0.96-1.11).

conclusionsAlthough the use of statins does not enhance the prevention of stroke recurrence in PWCS, statin treatment is associated with improved clinical outcomes in PWCS. Statins play a beneficial role in the treatment of cardioembolic stroke.
