Effects of obesity on post-surgical recovery and functional outcomes in rotator cuff tear repair.
Article in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Rotator cuff tears (RCTs) are a common cause of shoulder pain and can severely affect patients' ability to perform daily activities. Comorbidities, such as obesity, are known to influence the outcomes of RCT repair, particularly in the context of arthroscopic surgery. However, the effect of obesity on postoperative outcomes following RCT repair has not been sufficiently explored, especially in patients undergoing minimally invasive procedures. This study aims to evaluate the impact of obesity on postoperative pain, range of motion, and functional recovery after arthroscopic rotator cuff repair. Methods: This retrospective cohort study included 50 patients who underwent arthroscopic RCT repair between January 1, 2022, and January 1, 2025. All patients were followed for a minimum of two years postoperatively. Data collected included factors such as fatty infiltration (Goutallier grade), tendon retraction (Patte grade), obesity (BMI ≥ 30), education level, and smoking status. The primary outcomes assessed were postoperative pain (Visual Analog Scale, VAS), range of motion (active forward flexion and external rotation), UCLA Shoulder Score, and ASES Score. Results: The average age of the study participants was 59.9 ± 7.4 years, with 28% of patients being female. A total of 42 patients (84%) had a full-thickness rotator cuff tear. The median time from diagnosis to surgery was 22.5 months (IQR: 17.3-29.8 months), with a median follow-up duration of 30.2 months (IQR: 26.3-34.1 months). Eighteen patients (36%) were classified as obese (BMI ≥ 30). Obese patients demonstrated a trend toward higher postoperative pain (VAS: 4.8 ± 2.8 vs. 4.0 ± 3.2, Conclusion: This study found that obesity was significantly associated with reduced active forward flexion (
