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
objectiveThis study aimed to examine the discriminative capacity of the Dimensional Clinical Personality Inventory 2 (IDCP-2) factors for identifying individuals with elevated borderline personality disorder (BPD) traits within a Brazilian community sample while proposing an optimal cutoff score for distinguishing high BPD trait levels.
methodsThe participant cohort consisted of 1,469 adults who completed assessments, including the Level of Personality Functioning Scale - Brief Form 2.0 (LPFS), the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) (PID-5), the IDCP-2, and the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) - Personality Questionnaire (PQ-SCID-II). We categorized participants into three groups utilizing the traits outlined in the Alternative Model of Personality Disorders (AMPD) from DSM-5 Section III. Furthermore, latent profile analysis based on PID-5 facets revealed the existence of three empirically derived profiles.
resultsOur findings demonstrate that IDCP-2 factors exhibited substantial discriminative power, marked by large effect sizes across most factors. To minimize false negatives, we suggest a conservative cutoff score of 22 as the most effective threshold for identifying individuals with high levels of BPD traits.
conclusionThe BPD score generated from IDCP-2 factors holds significant promise in clinical practice, offering valuable insights into a patient's propensity to exhibit a BPD profile and providing a comprehensive clinical profile.
