Prevalence of suicidal behavior in nigeria: a systematic review and meta-analysis.
Synthesis in Scientific reports, 2026. 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
Suicidal behaviors are a major public health concern, yet their burden remains poorly defined in Nigeria, a country with a predominantly young population. This study aimed to comprehensively assess the prevalence and correlates of suicidal ideation, planning, and attempt in Nigeria. We systematically searched medical literature databases for studies published up to November 2025 that reported the prevalence of suicidal behaviors in the Nigerian general population or specific subgroups, using diagnoses or validated screening tools. Random-effects meta-analysis were conducted, with heterogeneity explored using meta-regression and subgroup analysis. Overall, 53 studies comprising 132,514 individuals were included. The prevalence of suicidal ideation in the general population was 7.9% (95%CI: 4.6, 13.4), while suicidal planning and attempts were estimated at 1.9% (95%CI: 0.9, 4.0) and 1.3% (95%CI: 0.4, 4.3), respectively. Suicidal ideation was associated with sociodemographic factors, including marital status, educational attainment, and employment status, and was more common in conflict-prone regions. Compared with the general population, suicidal behaviors were more prevalent among adolescents and young people, people living with HIV, and pregnant women. Notably, the prevalence also increased over time. These findings indicate that suicidal behaviors are common in Nigeria and highlight the need for targeted intervention strategies for high-risk populations.
