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

backgroundSecond-generation antipsychotics (SGAs) are often prescribed in the treatment of Behavioral and Psychological Symptoms of Dementia (BPSD), however, their use has been discouraged in light of clinical trials suggesting that they cause an increased risk of cerebrovascular accidents (CVAs).

objectiveAim of the study was to assess relative risk of CVA in dementia patients prescribed SGA rather than first-generation antipsychotics (FGAs), through meta-analysis of population-based studies.

methodsA literature search was conducted using several relevant databases. Five studies were included in the review and data were pooled to conduct meta-analysis using the inverse variance method.

resultsA total of 79,910 patients were treated with SGAs and 1287 cases of CVA were reported. Of 48,135 patients treated with FGAs, a total of 511 cases of CVA were reported. The relative risk of CVA was 1.02 (95% CI 0.56-1.84) for the SGA group. There was no significant difference in the risk of stroke (p = 0.96) between groups, but significant heterogeneity was found among the results of included studies (p < 0.001).

conclusionMeta-analysis of population-based data suggested that the use of SGAs as opposed to FGAs to control BPSD is not associated with significantly increased risk of CVA. Copyright © 2016 John Wiley & Sons, Ltd.
