Risk of self-harm in patients with body dysmorphic disorder: a population-based cohort study.
Article in Frontiers in psychiatry, 2025. 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
Objective: This study was conducted to determine whether individuals with body dysmorphic disorder (BDD) have an increased risk of self-harm behaviors compared with those without BDD. Methods: In this matched cohort study, we reviewed the electronic health records of all patients admitted for any reason to Hong Kong public hospitals between January 1, 1993, and December 31, 2022. We selected a cohort of 71 patients with BDD and a comparison cohort of 71 patients without BDD. Participants were followed until a diagnosis of self-harm, death from other causes, or the end of 2023, whichever occurred first. Cox proportional hazards regression models were used to assess the risk of self-harm since the onset of BDD. Results: During the 30-year study period, 2 (2.8%) individuals in the BDD group and 3 (4.2%) in the comparison group exhibited self-harm behavior. The proportion of individuals engaging in self-harm was similar between the groups (χ Conclusions: BDD is not associated with an increased risk of self-harm. Future studies are needed to replicate our findings and further identify potential risk factors for self-harm in patients with BDD.
