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: The optimal surgical management of displaced proximal humerus fractures in elderly patients remains controversial. Reverse total shoulder arthroplasty (rTSA) has gained increasing acceptance for complex fracture patterns, yet comparative data against open reduction and internal fixation (ORIF) across age strata are limited. This study compared reoperation rates, emergency department (ED) utilization, and dislocation following rTSA versus ORIF in propensity score-matched cohorts stratified by age. Methods: Using the TriNetX multi-institutional research network, patients aged 65-74 years and 75-84 years who underwent rTSA or ORIF for proximal humerus fractures were identified. Propensity score matching was performed using nearest-neighbor matching with a 0.150 standard deviation caliper. The primary outcome was coded shoulder-related return to surgery at 1 and 2 years. Secondary outcomes included all-cause ED utilization and coded dislocation when available. Results: After matching, 748 patients (374 per group) were analyzed in the 65 to 74-year cohort and 882 patients (441 per group) in the 75 to 84-year cohort. Patients undergoing rTSA had significantly more 4-part fractures (34.2% vs. 6.4% in the 65 to 74-year cohort, Conclusion: In propensity score-matched cohorts, rTSA and ORIF demonstrated comparable coded reoperation rates and all-cause ED utilization at 1- and 2-year follow-up. These findings persisted despite rTSA patients having more complex fracture patterns; however, because fracture morphology and patient-reported outcomes were not directly matched or captured, the results should be interpreted as hypothesis-generating real-world associations rather than evidence of treatment superiority.
