Hair stress hormones in individuals with a recent suicide attempt experiencing a depressive episode.

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: Stressful events and dysregulation of the hypothalamic-pituitary-adrenal (HPA)- axis contribute to the risk of suicide attempt (SA) in persons in depressive episodes. Hair cortisol, cortisone and dehydroepiandrosterone (DHEA) concentrations may serve as reliable indicators of HPA axis dysregulation prior to SA. Methods: Participants (n = 75; mean age [standard deviation] = 30.0 [10.2] years; n = 49 [65 %] women; Jena site) comprised three groups: individuals with a history of SA approximately one month (SA; n = 22); individuals with a current depressive episode without SA history (CC; n = 31) and healthy individuals (HC; n = 22). SA was defined as self-initiated, potentially injurious behavior accompanied by some intent to die. Stress hormones were measured using LC-MS/MS protocol (days from sampling to analysis = 342 [171]) and logarithmic transformed. Group differences in hair stress hormones with hair segments representing time were tested using linear mixed models on a p < .05 threshold. Exploratory models further examined the effects of childhood abuse, frequency of SAs, suicide intent level and impulsiveness of the last SA of mean hormone levels, on a corrected p Results: There was a main effect of group for the DHEA-log (p = .02) and post-hoc tests indicated that SA group had higher DHEA compared to CC (p Conclusions: Individuals with a recent history of SA showed alterations in the DHEA hair levels. These results partially support dysregulation of the HPA axis as a biopsychosocial feature of SA. Future longitudinal and experimental studies should investigate whether hair HPA axis hormones can serve as markers of suicidal crisis and vulnerability.
