The frequency and correlates of complex post-traumatic stress disorder among patients being treated for borderline personality disorder: cross-sectional study.
Article in BJPsych open, 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
backgroundDespite overlapping diagnostic criteria and aetiology, the frequency of complex post-traumatic stress disorder (C-PTSD) in people being treated for borderline personality disorder (BPD) is unknown.
aimsTo establish the frequency and correlates of probable C-PTSD in people meeting the diagnostic criteria and being treated for BPD.
methodC-PTSD was assessed in 87 patients meeting the diagnostic criteria for BPD and initiating treatment in out-patient personality disorder services in the UK, using the Structured Clinical Interview for DSM-IV Axis II Personality Disorders diagnostic interview, items from the Structured Interview for Disorders of Extreme Stress - Self Report and other measures. The cross-sectional association between C-PTSD and demographics, trauma and clinical variables was evaluated with logistic, ordinal and linear regression.
resultsA total of 93% of participants reported a trauma history (95% CI 88-98%), and 57% met the criteria for probable C-PTSD (95% CI 47-67%). Previous sexual trauma increased the odds of probable C-PTSD (odds ratio 6.22, 95% CI 2.21-17.54,
conclusionsC-PTSD symptoms are likely to be common in people diagnosed with BPD, and are associated with higher overall psychiatric severity, with potential implications for formulation and treatment.
