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

backgroundIschemic stroke (IS) remains a leading global cause of mortality, recurrence, and long-term disability, with survivors also at risk of post-stroke dementia (PSD) and cognitive impairment (PSCI). The precise impact of statin therapy across different IS populations, including those with cardioembolic/atrial fibrillation (CE/AF) strokes and patients with low-baseline low-density lipoprotein (LDL) cholesterol, remains unclear, as does the influence of statin timing, intensity, type, and solubility.

methodsWe conducted the Impact of Statin Therapy on the Risk of Stroke Recurrence, Mortality, and Dementia After Ischemic Stroke (ISMARDD) meta-analysis, synthesizing evidence from 51 studies (

resultsStatin therapy significantly reduced all-cause mortality within 3 months (OR 0.32), at 1 year (OR 0.35), and beyond 1 year (OR 0.56). Stroke recurrence was modestly reduced both within 1 year (OR 0.77) and after 1 year (OR 0.76). Statin use was associated with a lower risk of PSD (OR 0.74) but not PSCI overall. Benefits extended to CE/AF-related strokes and patients with low-baseline LDL cholesterol, both showing significantly lower mortality with statin use. Early initiation (<24 h) was linked with reduced recurrence, though effects of statin intensity, type, and solubility were inconsistent. Statins also significantly reduced CRP levels, underscoring anti-inflammatory and pleiotropic mechanisms.

conclusionsThe ISMARDD study demonstrates that statins confer survival benefit and selective cognitive protection (notably reduced PSD risk) after ischemic stroke, with modest recurrence benefit, supporting their broad use in secondary prevention. These findings highlight the need for precision-guided approaches tailored to stroke subtype, pharmacogenomics, and treatment timing to optimize therapeutic outcomes.
