Psychometric performance of the Patient-Reported Outcomes Measurement Information System-Physical Function and Oxford Shoulder Scores in total shoulder arthroplasty.

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: The Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF) and Oxford Shoulder Score (OSS) are frequently used patient-reported outcome measures in total shoulder arthroplasty (TSA); yet, direct psychometric comparison of these 2 measures has not been previously performed. The purpose of this study was to compare the psychometric properties of PROMIS-PF and OSS, measured at baseline and 6 months post-operatively, among patients undergoing primary TSA. Methods: A retrospective study of 70 patients undergoing anatomic or reverse TSA at a single institution (2021-2024) was performed. All patients included completed a pre-operative and a 6-month post-operative PROMIS-PF v2.0 short form 10a survey and OSS survey. Psychometric analysis was performed to compare internal consistency reliability, convergent construct validity, floor/ceiling effects, and responsiveness between measures. Results: Both PROMIS-PF and OSS demonstrated excellent internal consistency reliability and strong responsiveness. While both instruments had very low (<2%) floor/ceiling effects pre-operatively, some low-level ceiling effects were observed at 6-month follow up. A moderate correlation between measures was observed, demonstrating adequate construct validity given the intent of PROMIS-PF and OSS to measure general physical function and shoulder specific function, respectively. Conclusion: In patients undergoing TSA, PROMIS-PF and OSS demonstrated strong psychometric performance. As the 2 measures evaluate the unique but related constructs of general and shoulder-specific function, they displayed moderate correlation. Therefore, both PROMIS-PF and OSS hold value in assessing the outcomes of TSA patients and may be effectively used concurrently in practice.
