Data linkage studies on veteran suicidality: a scoping review of the field, knowledge gaps and evidence appraisal.
Article in BMC psychiatry, 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
BACKGROUND AND
aimsSuicidality among veterans is a serious issue that impacts veterans, their families, friends, and communities. Using data linkage to examine suicidality among veterans remains an emerging area. This review examines the application of data linkage to questions on suicidality among veterans from within the Five Eyes alliance to generate learnings that can be applied to the Australian context.
methodsThis scoping review was conducted in accordance with PRISMA guidelines. Peer reviewed databases and grey literature were searched. Studies were assessed against the Reporting of studies Conducted using Observational Routinely-Collected Data (RECORD) Statement.
results58 studies were included in the review. 60% of these were identified as being of good or excellent quality. Most (72.4%) were conducted in the US, followed by Canada (13.8%) and Australia (8.6%). The majority of studies examined suicide deaths (81%), while 31% assessed ideation, self-harm, or attempts. DISCUSSION: Studies were overwhelmingly health focussed, with examination of psychosocial determinants and social care pathways lacking. The literature was inconsistent in describing methods and there was no documented evidence of lived experience involvement.
conclusionThe review highlights benefits to undertaking data linkage research within the Australian context and has noted several gaps to address that could enhance the evidence-base globally. Enhancements to the RECORD statement are recommended. Enhancements in ethics, governance and information sharing protocols between institutions should be investigated to support more comprehensive linkages that facilitate the examination of longitudinal risk factors, health and psychosocial trajectories, service transitions, and multi-systemic influences on veteran suicidality. CLINICAL TRIAL NUMBER: Not applicable.
