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

objectivesApproximately, half of the acute stroke patients with minor symptoms were excluded from thrombolysis in some randomized controlled trials (RCTs). There is little evidence on treating minor strokes with rt-PA. Here, we performed a systematic review and meta-analysis to assess the safety and efficacy of thrombolysis in these patients.

methodsPubMed, Embase, Web of Science, and Cochrane Library were searched in July 2018. All available RCTs and retrospective comparative studies that compared thrombolysis with nonthrombolysis' for acute minor stroke (NIHSS ≤ 5) with quantitative outcomes were included.

resultsTen studies, including a total of 4,333 patients, were identified. The risk of intracranial hemorrhage (ICH) was higher in the rt-PA group as compared with that in the non-rt-PA group (3.8% vs. 0.6%; p = .0001). However, there is no significant difference in the rate of mortality between the two groups (p = .96). The pooled rate of a good outcome in 90 days was 67.8% in those with rt-PA and 63.3% in those without rt-PA (p = .07). Heterogeneity was 43% between the studies (p = .08). After adjusting for the heterogeneity, thrombolysis was associated with good outcome (68.3% vs. 63.0%, OR 1.47; 95% CI 1.14-1.89; p = .003). In post hoc analyses, including only RCTs, the pooled rate of good outcome had no significant differences between the two groups (86.6% vs. 85.7%, 95% CI 0.44-3.17, p = .74; 87.4% vs. 91.9%, 95% CI 0.35-1.41, p = .32; before and after adjusting separately).

conclusionsAlthough thrombolysis might increase the risk of ICH based on existing studies, patients with acute minor ischemic stroke could still benefit from thrombolysis at 3 months from the onset.
