Mental disorders and excess mortality: a systematic review protocol.
Article in BMJ open, 2025. 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
backgroundThere is developing evidence of excess mortality among people with mental disorders. This protocol presents the methodology to undertake a systematic review to definitively examine the current evidence on the risk of all-cause and cause-specific mortality in people with mental disorders (mood, anxiety, substance use, eating, personality and psychotic disorders) compared with populations without mental disorders in broadly representative studies of general populations worldwide. In addition, we seek to understand whether the excess mortality has increased further over time, and if the COVID-19 pandemic exacerbated the excess mortality in people with mental disorders.
methodsA systematic review of cohort studies will be conducted. The search strategy to yield peer-reviewed (in Medline Complete, CINAHL Complete, Embase and APA PsycInfo) and published grey literature will be developed in consultation with a liaison librarian. A preliminary scope of peer-reviewed literature in Medline Complete using the EBSCOhost platform was conducted on 20 November 2023. Epidemiological cohort or case-control studies will be eligible if they examine (1) diagnoses of mental disorders (according to the Diagnostic and Statistical Manual of Mental Disorders and the International Classification of Diseases classification systems) and (2) risk of all-cause and/or cause-specific mortality. A critical appraisal of the included studies will be undertaken. A synthesis of the findings will include the characteristics of the included studies, critical appraisal and a summary of the key findings in texts and visually in tables. Where appropriate, meta-analyses and subgroup analyses will be performed. ETHICS AND DISSEMINATION: This study is exempt from ethics approval, as it does not include identifiable human data. The outcomes of the proposed review will be shared in national/international conferences, published in a peer-reviewed journal and disseminated to new and existing networks. PROSPERO REGISTRATION NUMBER: CRD42023477494.
