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

backgroundThe impact of serum matrix metalloproteinases-9 (MMP-9) on cognitive impairment after ischemic stroke is unclear. We aimed to investigate the association between serum MMP-9 in the short-term acute phase of ischemic stroke and cognitive impairment at 3 months. METHODS AND

resultsOur study was based on a subsample from the CATIS (China Antihypertensive Trial in Acute Ischemic Stroke); a total of 558 patients with serum MMP-9 levels from 7 of 26 participating sites of the trial were included in this analysis. Cognitive impairment severity was categorized as severe, mild, or none (Mini-Mental State Examination score, <23, 23-26, or ≥27, respectively; Montreal Cognitive Assessment score, <20, 20-24, or ≥25, respectively). Cognitive impairment was defined as a score of <27 for Mini-Mental State Examination or <25 for Montreal Cognitive Assessment. According to Mini-Mental State Examination score, 143 participants (25.6%) had mild cognitive impairment and 153 (27.4%) had severe cognitive impairment at 3 months. After adjustment for age, National Institutes of Health stroke score, education, and other covariates, the odds ratio for the highest quartile of serum MMP-9 compared with the lowest quartile was 3.20 (95% confidence interval, 1.87-5.49) for cognitive impairment. Multiple-adjusted spline regression model showed a linear association between MMP-9 levels and cognitive impairment (

conclusionsIncreased serum MMP-9 levels in the short-term phase of ischemic stroke were associated with 3-month cognitive impairment, independently of established risk factors.
