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

objectivesParticipatory organizational interventions (POIs) may improve workers' mental health and work performance, but evidence from systematic reviews and meta-analyses of cluster-randomized controlled trials (cRCTs) remains limited. The meta-analysis has not been updated since it was published in 2015; a previous study focused on health care workers; and potential outcomes have not been adequately examined. This systematic review and meta-analysis aimed to investigate the effects of POIs on mental health and work performance among workers.

methodsThe current study searched PubMed, EMBASE, PsycINFO, PsycARTICLES, and Japan Medical Abstracts Society for papers published up until November 11, 2022. Eligible studies were cRCTs assessing the effects of POIs on mental health or work performance. The risks of bias were evaluated by using the Cochrane risk-of-bias tool for cRCTs and meta-analysis was performed using a random effects model.

resultsFourteen cRCTs were included in the systematic review, and 8 cRCTs in the meta-analysis. The meta-analysis showed a nonsignificant beneficial effect on mental health conditions [standardized mean difference (SMD) = -0.04; 95% CI, -0.10 to 0.03], positive mental health (SMD = -0.004, 95% CI, -0.077 to 0.068), and work performance (SMD = 0.01; 95% CI, -0.10 to 0.13).

conclusionsThis study did not confirm that POIs had a statistically significant effect on mental health or work performance. However, several studies that reported favorable results tended to emphasize active and structured participation, alignment with workers' needs, and attention to organizational context. Further research is needed to identify the conditions under which the interventions are effective.
