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: Total shoulder arthroplasty (TSA) has seen a dramatic rise in utilization, particularly in the elderly population. While indications have expanded beyond glenohumeral osteoarthritis (OA) to include proximal humerus fractures (PHFs), robust evidence comparing outcomes between these groups remains limited. We sought to compare the rate of surgical and medical complications of TSA (reverse or anatomic) performed for PHFs versus OA in elderly patients at 1 and 3 years post-operatively. Methods: The TriNetX Global Collaborative Network, comprising 183 million patients across 155 healthcare organizations, was retrospectively queried for patients aged ≥65 years undergoing TSA. Two mutually exclusive cohorts were identified: patients undergoing TSA within 3 weeks of a PHF diagnosis (PHF cohort) or those with a pre-existing diagnosis of OA (OA cohort). Exclusion criteria included age <65 years, concurrent diagnoses of PHF and OA, and polytrauma. Patients were propensity score matched 1:1 on demographics and comorbidities. Outcomes assessed included surgical complications (infection, periprosthetic fracture, prosthetic failure, reoperation, persistent pain, and opioid use) and medical complications (cardiac, thromboembolic, respiratory, infectious, and mortality) at 1 and 3 years post-operatively. Results: A total of 57,203 TSA patients were identified, 52,597 (91.9%) for OA and 4,606 (8.1%) for PHFs. Following propensity matching, 9,190 patients (4,595 per cohort) were analyzed. At 1 year, PHF patients exhibited higher rates of nearly all complications, including periprosthetic fracture, prosthesis-related complications, readmission, emergency department visits, transfusion, and opioid use ( Conclusion: Elderly patients undergoing TSA for PHFs face substantially greater risks of post-operative complications and healthcare utilization compared to those treated for OA, despite reporting lower rates of persistent pain at 1 and 3 years. These findings highlight the need for tailored perioperative management, risk counseling, and careful patient selection in this vulnerable population.
