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
Objectives: This study aimed to translate, culturally adapt, and validate the Patient and Observer Scar Assessment Scale (POSAS) for Persian-speaking populations, ensuring its applicability and reliability in both clinical and research settings in Iran. Methods: The cross-cultural adaptation process involved forward and backward translations, expert panel reviews, and pre-testing. A total of 60 post-surgical patients participated in the study. Psychometric evaluations included content validity, internal consistency, and test-retest reliability. Content Validity Ratios (CVRs) and Content Validity Indices (CVIs) were calculated, with thresholds set at 0.51 and 0.79, respectively. Reliability was assessed using Cronbach's alpha coefficients (≥0.7) and test-retest stability over a two-week interval. Results: The Persian POSAS demonstrated robust psychometric properties. All items exceeded the CVI threshold, achieving strong expert consensus (CVR ≥0.51). Cronbach's alpha coefficients were 0.88 and 0.81 for the Observer Scar Assessment Scale (OSAS) and Patient Scar Assessment Scale (PSAS), respectively, indicating high internal consistency. Test-retest reliability confirmed stability over time. These results were consistent with previous adaptations in other languages, including Arabic and Italian. Conclusion: The Persian adaptation of POSAS is a valid and reliable tool for scar assessment, filling a critical gap in patient-centered care for Persian-speaking populations. This tool enables standardized evaluation of scars and supports clinical research. Future studies should explore its responsiveness to therapeutic interventions and its applicability across diverse patient demographics.
