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: Anatomic total shoulder arthroplasty (aTSA) has been proven effective in the treatment of painful end-stage osteoarthritis in patients with intact rotator cuff function. However, elderly patients may have an increased risk of revision, especially when it comes to the risk of revision due to loosening, rotator cuff pathology and periprosthetic fracture. The aim of this study was to investigate revision rates and patient-reported outcomes after aTSA for osteoarthritis in patients who are 75 years or older. We hypothesized that revision rates and patient-reported outcomes were similar for patients aged 55-74 years and 75 years or older. Methods: This is a registry-based cohort study with data from the Danish Shoulder Arthroplasty Registry. For analysis, 1,884 aTSAs used for osteoarthritis between January 1, 2012, and December 31, 2019, were included. Patients were divided into 2 age groups: 55-74 years and 75 years or older. The Kaplan-Meier method was used to estimate unadjusted cumulative revision rates and a multivariate Cox regression model was used to determine hazard ratios. A multivariable linear regression model was used to compare the Western Ontario Osteoarthritis of the Shoulder Index (WOOS) 1 year postoperatively. Results: There were 34 (2.5%) patients in the middle-aged group and 8 (1.6%) patients in the older age group who had revision surgery. The hazard ratio for revision was 0.67 for the older age group compared to the middle-aged group (95% confidence interval [CI] 0.31-1.47, Conclusion: We found low short-term revision rates and good patient-reported outcomes for both middle-aged and older patients treated for osteoarthritis using aTSA. The small differences in WOOS between the 2 age groups were not clinically relevant nor statistically significant. aTSA provides good and reliable outcomes in elderly patients with end-stage osteoarthritis, and age alone should not be a reason for opting out aTSA.
