Psychometric Properties of Full and Shortened Persian-version of Western Ontario Rotator Cuff Index Questionnaires in Persian-speaking Patients with Shoulder Pain.

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
Background: This study aimed to translate the shortened Western Ontario Rotator Cuff (Short-WORC) questionnaire into Persian and determine the psychometric features of WORC and Persian-Short-WORC in patients with shoulder pain. Methods: A total of 130 patients completed Persian-WORC and -Short-WORC, Shoulder Pain And Disability Index (SPADI), shortened Disability of Arm, Shoulder, and Hand (Quick-DASH), WORC, as well as Short-Form health survey (SF-36), in the evaluation and re-evaluation sessions with an interval of 5-7 days to assess reliability and validity. To determine responsiveness, all patients completed questionnaires and a global rating of change scale before and after the 4-week physiotherapy. Intra-class correlation coefficient (ICC) was used for assessing reliability, two-tailed Pearson ( Results: The ICC was 0.95 (confidence interval: 0.93-0.96) for Short-WORC. A strong correlation was found between Short-WORC, SPADI (r=-0.82), Quick-DASH (r=-0.79), WORC (r=0.92), SF-36 physical (r=0.76), and SF-36 mental (r=0.71). Floor and ceiling effects were not detected. The responsiveness of Short-WORC and WORC was proven with an area under the curve of >0.90, and their minimal important change was 28.56 and 26.28 points, respectively. Conclusion: The Persian version of WORC has good psychometric properties to measure disability and health-related quality of life in patients with shoulder pain.
