Mental health of internally displaced persons: a meta-analysis.
Synthesis in BMJ global health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionAlthough most forcibly displaced individuals remain within their country of origin, internally displaced persons (IDPs) remain under-represented in mental health research. We estimated the prevalence of mental disorders among IDPs and compared prevalence and psychosocial functioning with non-displaced controls.
methodsWe searched MEDLINE, PsycINFO and Web of Science for peer-reviewed reports published until 20 June 2025 in any language. We included studies on point prevalence of mental disorders in adult IDPs as assessed with validated measurements based on the International Classification of Diseases or Diagnostic and Statistical Manual of Mental Disorders. Studies had to assess mental disorders in at least 100 participants at least 1 month postdisplacement. For studies that included non-displaced control groups, we also assessed other mental-health-related outcomes. All analyses used a random effects model. The protocol was registered with PROSPERO, CRD42024596202.
resultsWe identified 20774 unique study reports, of which 132 (124 independent datasets and 195 741 participants, with 61.3% female IDPs) met our inclusion criteria. The estimated pooled prevalence of current post-traumatic stress disorder (PTSD) was 39.8% (95% CI 34.9% to 44.8%; I²=98.9%), depression 35.8% (95% CI 27.0% to 45.8%; I²=99.3%), generalised anxiety disorder 29.4% (95% CI 20.3% to 40.5%; I²=99.4%), insomnia 38.6% (95% CI 33.2% to 44.2%; I²=95.5%), panic disorder 6.0% (95% CI 2.7% to 12.9%; I²=95.9%), alcohol use disorder 2.2% (95% CI 0.1% to 6.2%; I²=97.3%) and suicidality 9.2% (95% CI 1.3% to 44.1%; I²=99.2%). The odds of PTSD and depression compared with non-displaced controls were increased by 70%-117% and IDPs reported significantly higher somatic complaints and general distress and lower psychosocial well-being. Displacement cause and socioeconomic conditions in the affected countries insufficiently explained the large heterogeneity in findings. High risk of selection and outcome measurement bias was observed.
conclusionsThe results highlight the mental health burden in IDPs, which calls for scalable and sustainable interventions. The findings further indicate that estimates vary substantially across contexts.
