Responses to social defeat in early- vs late-onset suicidal behavior: An experimental behavioral study.
Article in Comprehensive psychiatry, 2026. 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
backgroundSocial defeat is often cited as a motive for suicide. The experience of defeat may arise from feeling dominated in a dyadic conflict or from losing status in a group. We hypothesize that sensitivity to dyadic defeat will be related to the onset of suicidal behavior in early or mid-life and sensitivity to loss of status, in late life.
methodsThe study's sample of 245 adults aged 50 years and older (mean = 63.2 years, SD = 7.4) comprised 42 early-onset and 32 late-onset suicide attempters (aged < 50 vs ≥ 50 years at their first suicide attempt), 114 depressed non-attempter comparisons, and 57 non-psychiatric comparisons. Using a validated rigged video game tournament task, we operationalized compensatory responses to the two forms of social defeat as point stealing from individual opponents (one-on-one defeat) and rank buying in the league table (loss of status in a group).
resultsEarly-onset attempters increased point stealing the most over time (χ
conclusionsOur behavioral findings suggest that socio-behavioral processes leading to suicide vary across the life cycle. While vulnerability to dyadic defeat could be suicidogenic for people of any age, loss of social status could play a role in suicidal crises specifically occurring in later life.
