Prevalence of suicidal thoughts and behaviors among individuals with mental disorders in Africa: a systematic review and meta-analysis of the past 25 years.

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
backgroundSuicide causes over 800,000 deaths globally each year, with 73% occurring in low- and middle-income countries (LMICs). However, data on suicidal thoughts and behaviors (STBs) among individuals with psychiatric disorders in Africa remain limited. This study aims to assess the prevalence of STBs in this population using both general and clinical samples, addressing key data gaps in the African context.
methodsThis systematic review and meta-analysis searched PubMed, Web of Science, Scopus, and other databases from January 2000 to January 2025. Study selection followed PRISMA guidelines, with Rayyan and Zotero used for screening and duplicate removal. Data were extracted using a structured framework, and study quality was assessed with Joanna Briggs Institute tools. Statistical analyses, including I² heterogeneity evaluation, were conducted in R using a random-effects model.
resultsEighty-two studies (n= 24,687) were included in the final meta-analysis. Recent suicide attempts (SA) prevalence was at 9% (95% CI: 6–12%, I² = 91%): substance-related disorders (17%), bipolar (15%), depressive disorders (14%), and schizophrenia spectrum disorders (6%). Lifetime SA prevalence was at 24% (95% CI: 21–27%, I² = 95.3%): cluster B personality disorders (33%), substance-related disorders (28%), schizophrenia spectrum disorders (27%), bipolar disorders (25%), and trauma-related disorders (25%). Recent suicidal ideation (SI) was at 31% (95% CI: 25–37%, I² = 97.5%): bipolar (61%), trauma-related disorders (58%), anxiety disorders (44%), depressive disorders (36%), and schizophrenia spectrum disorders (20%). Lifetime SI was 40% (95% CI: 33–46%, I² = 98.4%): patients with schizophrenia (41%), bipolar disorders (40%), and depressive disorders (39%).
conclusionsSTBs among African individuals with psychiatric disorders represent a serious public health concern. These findings are essential for guiding targeted mental health policies and refining global STBs estimates.
