Trauma subgroups among individuals with eating disorders: a latent profile analysis.
Article in Journal of eating disorders, 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
objectiveTrauma-related symptoms are known to be highly prevalent in eating disorder (ED) populations but there has been limited research on complex post-traumatic stress disorder (CPTSD). The current study used latent profile analysis to examine trauma-related subgroups among clients with EDs and associations with ED severity and other outcomes.
methodsParticipants (N = 378) attending residential, day program, and outpatient ED services completed measures of ED symptoms, body mass index (BMI), ED-related impairment, depression, anxiety, and trauma-related symptoms (based on ICD-11 PTSD and CPTSD criteria, and dissociation) at admission.
resultsLatent profile analysis identified four trauma profiles: 1) high disturbances in self-organisation (DSO), 2) CPTSD (high on both PTSD and DSO symptoms, and severe dissociation), 3) general distress (moderate outcomes across all domains), and 4) no/mild trauma-related symptoms. After adjusting for level of care, profiles significantly differed on all outcomes except BMI, ED diagnosis, and objective binges. Groups 1 and 2 reported more severe ED and comorbid symptoms than groups 3 and 4, with group 2 also being more severe than group 1 on total ED psychopathology, eating concerns, purging, and anxiety. DISCUSSION: Findings support previous research on the high prevalence of trauma-related symptoms in EDs, with DSO symptoms (unique to CPTSD) appearing to drive much of the association with ED symptom severity. ED services may benefit from targeted use of trauma-focused therapies for individuals presenting with high DSO symptoms, both in the presence and absence of severe PTSD symptomatology.
