The impact of supraspinatus tear on subscapularis muscle atrophy and fatty infiltration.
Article in Clinics in shoulder and elbow, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundAimed to report the prevalence and predisposing factors affecting subscapularis muscle atrophy and fatty infiltration (MAFI) in patients without a subscapularis tear, and to analyze the effect of this condition on surgical outcomes.
methodsBetween 2020 and 2022, 153 patients (mean age 58.1 ± 10.2 years; 84 men and 69 women) who underwent repair of posterosuperior cuff tears, with no subscapularis tears identified during arthroscopy were retrospectively analyzed. Baseline characteristics, preoperative and follow-up (6 months) magnetic resonance imaging findings, arthroscopic findings, and clinical outcomes (>1 year) were recorded.
resultsThe prevalence of subscapularis MAFI (Goutallier grade 1 or 2) was 73.9% (113/153), of which the prevalence of Goutallier grade 2 was 23.5% (36/153). From multivariable logistic regression analysis, female sex (odds ratio [OR], 5.6; 95% CI, 1.7-18.6; P=0.005), older age (OR, 1.1; 95% CI, 1.0-1.1; P=0.052), advanced supraspinatus MAFI by Goutallier grade (OR, 3.2; 95% CI, 1.5-6.9; P=0.004), and synovitis (OR, 2.8; 95% CI, 1.1-7.9; P=0.030) were identified as independent predisposing factors for subscapularis MAFI. However, patients with preoperative subscapularis MAFI exhibited similar final range of motion, pain and function, and belly press strength compared to those without preoperative subscapularis MAFI.
conclusionsSubscapularis MAFI is frequently observed conditions even in the absence of subscapularis tears, and this condition could be affected by supraspinatus MAFI, female sex, older age, and synovitis. However, because subscapularis MAFI does not affect the surgical outcome, surgeons need not be concerned about this condition when repairing posterosuperior rotator cuff tear. Level of evidence: IV.
