Patients posture affects clinical outcomes and range of motion after reverse total shoulder arthroplasty: A clinical study.
Article in JSES international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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: Movement limitations following implantation of reverse total shoulder arthroplasty (rTSA) have been observed in some patients postoperatively, with implant design and positioning recognized as important influential factors. Recent analyses have identified patient's posture, measured as scapula internal rotation on computed tomography (CT), as an additional factor influencing the functional outcome after rTSA. However, no clinical study has correlated the preoperatively photo-documented posture to functional outcome. It was the aim of this study to correlate preoperatively photo-documented posture to scapula orientation using CT and analyze the influence on functional outcome following rTSA implantation. Methods: A prospectively enrolled rTSA database was retrospectively reviewed to include a total of 360 patients with a minimum follow-up of 2 years. Patient's posture was analyzed using standardized preoperative photo and video documentation. The posture was defined following the classification system of Moroder et al as type A (upright posture, retracted scapulae), type B (intermediate), and type C (kyphotic posture with protracted scapulae). In addition, CT data were used to measure scapula position (internal rotation). Correlation analyses between them were conducted. Postoperative range of motion (ROM) and clinical outcomes (absolute Constant-Murley Score and relative Constant-Murley Score) were compared between the different posture types. Results: According to the photo-documented posture types, the patients were divided into posture types A (n = 59), B (n = 253) and C (n = 48). Average absolute Constant-Murley Score differed significantly among the groups (69 ± 16 vs. 69 ± 14 vs. 64 ± 16, Conclusion: Patients with clinical posture types A and B exhibited improved ROM values compared to type C postures. Clinical outcome scores were also notably superior in types A and B. However, the measurement of scapula internal rotation on supine CT does not reliably correlate with photo documentation of patient's posture. Preoperatively, patient's posture should be considered in rTSA planning because of the potential influence on ROM and clinical outcomes.
