Borderline personality disorder in Trichotillomania and skin picking disorder: a survey study.
Article in BMC psychology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundComorbidity studies in trichotillomania and skin picking disorder (known as Body-Focused Repetitive Behaviors, BFRBs) have traditionally not examined rates of borderline personality disorder. When it co-occurs, borderline personality disorder may necessitate different treatment approaches and if untreated may interfere with the response to the treatment for trichotillomania or skin picking disorder. The objectives of this study were to (1) examine the rate of co-occurring borderline personality disorder in BFRBs; and (2) explore associations between co-occurring borderline personality disorder and relevant clinical characteristics (such as demographic features, BFRB symptom severity, lifetime history of suicide attempt[s], levels of dissociation, and other comorbidities including impulsive conditions that are often unmeasured in studies).
methodsAdults with skin picking disorder, trichotillomania, or both completed an online survey. The survey was comprised of demographic and clinical questions, plus instruments to measure for probable borderline personality disorder, as well as BFRB severity, dissociation, impulse control conditions (including BFRBs), and alcohol use disorder. Each participant also completed questions about previous formal mental health diagnoses.
resultsOf the 281 adults with BFRBs (n = 105 with skin picking disorder; 93 with trichotillomania, and 82 with both disorders), 105 (37.4%) screened positive for a probable diagnosis of borderline personality disorder. Participants screening positive for probable borderline personality disorder reported significantly worse pulling and picking symptoms (p < .001), higher rates of dissociation (p < .001), and were significantly more likely to report lifetime suicide attempts (p < .001) and to endorse co-occurring alcohol problems (p < .001), compulsive buying disorder (p < .001), gambling disorder (p < .001), compulsive sexual behavior (p < 001), and kleptomania (p = .005).
conclusionsThese data suggest relatively high rates of borderline personality disorder in people with BFRBs, in turn linked to more severe psychopathology and elevated lifetime suicide attempt risk. Perhaps the comorbidity with borderline personality disorder reflects a possible subtype of these behaviors that is more impulsive and may necessitate different treatment approaches.
