Early complications and risk factors following reverse versus anatomic total shoulder arthroplasty for osteoarthritis: a nationwide registry study.
Article in Clinics in shoulder and elbow, 2025. 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
backgroundReverse shoulder arthroplasty (RSA) is an alternative to anatomic total shoulder arthroplasty (TSA) for treating glenohumeral osteoarthritis (OA), particularly in elderly patients. This study evaluates 90-day postoperative complication rates and identifies risk factors for adverse outcomes in RSA and TSA patients.
methodsA retrospective cohort study was conducted using the TriNetX Research NLP Network to identify patients aged 65-90 years who underwent RSA or TSA for OA from 2006 to 2024. 1:1 propensity score matching controlled for demographics and comorbidities. Orthopedic and infectious complications were compared using multivariate logistic regression.
resultsThe final matched cohort included 4,117 RSA and TSA patients. RSA was associated with significantly higher odds of orthopedic complications compared to TSA. Significant risk factors for orthopedic complications in RSA included nicotine dependence (OR, 1.592; P=0.001) and hypertension (OR, 1.545; P=0.001). In TSA, risk factors included male sex (OR, 0.702; P=0.005), chronic obstructive pulmonary disease (OR, 1.650; P=0.016), and obesity (OR, 1.776; P<0.001). For infections, RSA risk factors were male sex (odds ratio [OR], 1.698; P=0.005), heart failure (OR, 2.396; P<0.001), and diabetes (OR, 1.525; P=0.039). Diabetes was the only significant risk factor in TSA (OR, 2.453; P=0.003).
conclusionsRSA carries a higher risk of orthopedic complications and infection than TSA within 90 days. Distinct risk factors for each procedure highlight the need for patient-specific risk stratification to optimize preoperative assessment and surgical decision-making. Level of evidence: III.
