Synchronous remote-based interventions for suicidal behaviour prevention: a systematic review and meta-analyses of clinical trials.
Synthesis in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectivesSuicide is a leading cause of preventable death worldwide. Evidence supports the impact of providing active contact for individuals who have attempted suicide. The current systematic review and meta-analyses aim to investigate the effects of suicide prevention strategies implemented through remote and synchronous technology-based interventions.
designSystematic review, narrative synthesis and meta-analysis. DATA SOURCES: Electronic databases (PubMed, PsycINFO, Scopus and Web of Science) and grey literature sources (ClinicalTrials.gov and Google Scholar) were searched until December 2024. ELIGIBILITY CRITERIA: Eligible articles assessed suicide prevention interventions for participants over 12 years with prior suicidal behaviour. Eligible study designs included randomised controlled trials and non-randomised clinical trials published in English or Spanish. DATA EXTRACTION AND SYNTHESIS: Screening, selection process, data extraction and risk of bias assessment were performed independently by two reviewers. Data on suicide-related factors and adherence to treatment were extracted. Meta-analyses were conducted to determine effect sizes (Hedges' g) for suicidal ideation, risk ratios (RR) for suicide attempts and Peto odds ratios (OR) for suicide. Heterogeneity was assessed using the Cochrane's Q test, tau
resultsA total of 28 studies, comprising 10 015 participants in the intervention group and 10 726 in the comparison group, were included in the systematic review and meta-analyses. Synchronous remote-based interventions were effective in preventing repeated suicide attempts at 1 month (RR 0.73, 95% CI 0.62 to 0.85, I
conclusionsSynchronous remote-based interventions demonstrate a potential benefit in preventing suicide attempts and deaths by suicide and may serve as an adjunct to usual treatment; however, the effect on suicidal ideation appears limited. The observed heterogeneity warrants caution when interpreting these findings. Future research should prioritise methodological enhancements to improve the quality and consistency of evidence, as well as investigate the mediating processes underlying their effectiveness in reducing suicidal behaviour.
