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

objectiveBipolar disorder (BD) may be associated with an increased risk of stroke, but to date, the results of the studies are still controversial. This study aimed to assess the association of BD with stroke incidence and mortality by a meta-analysis.

methodPubMed, EMBASE, the Cochrane library databases, and Web of Science databases were searched from inception to July 2020. We regarded stroke as a composite endpoint. The pooled hazard ratio (HRs) of 95% confidence interval (Cls) was calculated. Subgroup and sensitivity analyses were performed to assess the potential sources of heterogeneity of the pooled estimation.

resultsA total of 7 studies involving a total of 13,305,007 participants were included in this meta-analysis. Pooled analysis showed participants with BD experienced a significantly increased risk of both stroke incidence (combined HR, 1.43; 95% CI, 1.24-1.66; p = 0.000) and stroke mortality (combined HR, 1.54; 95% CI, 1.09-2.18; p = 0.013) compared to participants without BD. In addition, the pooled estimate of multivariate HRs of stroke incidence and mortality were 1.35 (95% CI: 1.26-1.45); 2.30 ( 95% CI: 1.37-3.85) among men and 1.43 (95% CI:1.27-1.60); 2.08 (95% CI:1.60-2.71) among women respectively.

conclusionsThis meta-analysis suggests that BD may modestly increase the risk of both stroke incidence and mortality. Extensive clinical observational studies should be conducted in the future to explore whether BD is a potentially modifiable risk factor for stroke.
