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
objectiveThe aim of this study was to evaluate the validity and reliability of the Turkish version of the Clinical Perfectionism Questionnaire (CPQ-TR) in clinical and non-clinical samples.
methodThis cross-sectional study included 63 clinical participants (Obsessive–Compulsive Disorder and Major Depressive Disorder) and 148 non-clinical participants. The scale adaptation was conducted using a translation–back translation procedure. Confirmatory factor analysis and internal consistency analyses were performed. Convergent and concurrent validity were examined through correlations with the Frost Multidimensional Perfectionism Scale (FMPS), Depression Anxiety Stress Scales–21 (DASS–21), and the Yale–Brown Obsessive Compulsive Scale (Y-BOCS).
resultsThe internal consistency of the original 12-item CPQ-TR was found to be at a borderline level (Cronbach’s α=0.677); following the removal of Items 2 and 8, the Cronbach’s alpha coefficient of the resulting 10-item form increased to 0.76. Confirmatory factor analysis indicated limited support for a unidimensional factor structure. The CPQ-TR showed strong correlations with the FMPS (r=0.593) and moderate correlations with the Y-BOCS and DASS-21 (r=0.30–0.35). Participants with Obsessive–Compulsive Disorder had significantly higher CPQ scores compared to those with Major Depressive Disorder (p=0.018) and healthy controls (p <0.001).
conclusionThe findings indicate that the 12-item CPQ-TR demonstrates borderline internal consistency but remains a valid instrument for assessing clinical perfectionism. The 10-item version appears to be a more psychometrically robust option for use in both research and clinical settings.
