Effect of Comorbidities on Short-Term Postoperative Complications Following total Shoulder Arthroplasty: A TriNetX Study.
Article in Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews, 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
purposeAlthough nonmodifiable medical comorbidities are known to increase postoperative risk following total shoulder arthroplasty (TSA), the impact of potentially modifiable behavioral risk factors is less established. This study evaluated the effects of ischemic heart disease (IHD), type II diabetes mellitus (T2DM), cannabis use disorder (CUD), and nicotine dependence (ND), on short-term postoperative complications following TSA.
methodsThis retrospective cohort study used the TriNetX US Collaborative Network to identify patients undergoing primary TSA from 2004 to 2024 using CPT codes. Patients were stratified into cohorts according to ICD-10-CM diagnoses of IHD, T2DM, CUD, and ND. Propensity score matching (1:1) was done to balance baseline demographics and BMI. The primary outcome was 90-day complications.
resultsAmong 59,473 patients included, each comorbidity cohort showed notable increases in complications. Patients with IHD had greater odds of postoperative cardiac arrest (OR 6.825, CI, 3.513 to 13.26), acute kidney failure (OR 3.642, CI, 3.108 to 4.268), and pneumonia (OR 2.892, CI, 2.411 to 3.467). Patients with CUD had the highest odds of acute kidney failure (OR 2.539, CI, 1.556 to 4.143). T2DM was associated with increased skin infections (OR 2.151, CI, 1.806 to 2.562) and cardiac arrest (OR 3.159, CI, 1.692 to 5.898), whereas ND was associated with higher rates of pneumonia (OR 2.081, CI, 1.651 to 2.624) and acute kidney failure (OR 1.893, CI, 1.535 to 2.334).
conclusionBoth nonmodifiable comorbidities and modifiable risk factors markedly increase the risk of specific 90-day postoperative complications following TSA. These findings support targeted preoperative risk stratification and suggest optimizing CUD and ND may improve perioperative outcomes, although prospective studies are needed.
