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

This study was performed to evaluate the effects of exercise on positive and negative symptoms and depression in patients with schizophrenia through a systematic review and meta-analysis focusing on randomized controlled trials (RCTs). PubMed, Embase, CINAHL, MEDLINE, Cochrane Library, PsycINFO, and Web of Science were searched from their inception to 31 October 2022. We also conducted a manual search using Google Scholar. This meta-analysis was conducted according to the PRISMA guidelines. The methodological quality of the studies was assessed using the Cochrane risk-of-bias tool for randomized trials. To identify the cause of heterogeneity, subgroup analysis, meta-ANOVA, and meta-regression analyses were performed as moderator analyses. Fifteen studies were included. The meta-analysis (random-effects model) for overall exercise showed a medium significant effect (standardized mean difference [SMD] = -0.51, 95% confidence interval [CI]: -0.72 to -0.31) on negative symptoms, a small significant effect (SMD = -0.24, 95% CI: -0.43 to -0.04) on positive symptoms, and a nonsignificant effect (SMD = -0.87, 95% CI: -1.84 to 0.10) on depression. Our findings demonstrate that exercise can relieve the negative and positive symptoms of schizophrenia. However, the quality of some included studies was low, limiting our results for clear recommendations.
