1 · What the graph read from it

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.

2 · The registry

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

objectivesCanadian Armed Forces (CAF) Veterans and former Royal Canadian Mounted Police (RCMP) members ("Veterans/former RCMP members") may be at increased risk of mental health disorders necessitating psychiatric hospitalization relative to non-Veterans. Differences in occupational experiences may further influence risk across subgroups of Veterans/former RCMP members. We compared the likelihood of a psychiatric hospitalization between Veterans/former RCMP members and non-Veterans residing in Ontario, Canada: (1) overall; by (2) sex and (3) length of service.

methodsThis retrospective cohort study used administrative healthcare data to exact-match non-Veterans to Veterans/former RCMP members (4:1) residing in Ontario between March 18, 2002, and March 31, 2020, on age, sex, geography, and income. Sex-stratified Fine-Gray regression models were used to estimate the adjusted hazard ratio (aHR) of psychiatric hospitalizations within the first 10 years of follow-up.

resultsIn total, 2.5% of the 18,841 Veterans/former RCMP members (n = 476) and 0.9% of the 75,364 non-Veterans (n = 663) included in this study had a psychiatric hospitalization within the first 10 years of follow-up. Veterans/former RCMP members had a higher aHR of psychiatric hospitalizations than non-Veterans (aHR, 2.93; 95% CI, 2.61-3.29). Effects were stronger among females (aHR, 4.54; 95% CI, 3.34-6.17) and those with fewer years of service (e.g. 5-9 years aHR, 5.78; 95% CI, 4.27-7.83).

conclusionThe risk of psychiatric hospitalizations is almost three times higher among Veterans/former RCMP members compared to non-Veterans, with larger effects among females and individuals with fewer years of CAF/RCMP service. These occupational subgroups may benefit from targeted healthcare planning and resources.
