Cancer-related mortality among individuals with schizophrenia: systematic review and meta-analysis of cohort studies.
Review in BJPsych open, 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
backgroundIndividuals with schizophrenia have shown distinct cancer incidence patterns.
aimsWe aimed to assess whether their cancer-related mortality differs from the general population overall, by gender and by specific cancer types.
methodWe systematically searched Scopus, Web of Science, PsycINFO, PubMed and Embase, up to December 2025. Each record was independently screened by two reviewers, and data were independently extracted by two investigators. Two authors assessed the quality of the included articles with the Newcastle-Ottawa Scale. Analyses were conducted using Stata version 16; between-study heterogeneity was evaluated with Cochran's
resultsMeta-analysis of cohort studies showed that individuals with schizophrenia had a 55% higher risk of cancer-related death than the general population (standardised mortality ratio (SMR) 1.55; 95% CI 1.16-2.07). In gender-stratified analyses, SMRs for all cancers combined were 1.37 (95% CI 1.01-1.87) in men and 1.43 (95% CI 1.15-1.79) in women. Site-specific SMRs were 1.77 (95% CI 1.17-2.68) for breast, 2.40 (95% CI 2.35-2.45) for respiratory, 1.54 (95% CI 1.35-1.76) for gastrointestinal, 2.32 (95% CI 0.72-7.45) for haematologic, 4.43 (95% CI 0.71-27.62) for skin and soft tissue, 3.03 (95% CI 1.96-4.69) for urogenital and 1.01 (95% CI: 0.36-2.83) for other cancers, although precision varied considerably across cancer sites.
conclusionsSchizophrenia was associated with substantially elevated cancer-related mortality compared with the general population. These findings underscore the need for earlier cancer detection and guideline-concordant, integrated physical and mental healthcare for this high-risk group.
