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
purposeThe outcomes of shoulder hemiarthroplasty are highly dependent on the baseline glenoid morphology and the rotator cuff integrity. The objective of this study was to assess whether certain glenoid parameters and implant overstuffing are associated with worse clinical outcomes following shoulder hemiarthroplasty.
methodsWe retrospectively reviewed 25 patients who underwent shoulder hemiarthroplasty for shoulder arthritis, with a mean follow-up of 5.3 years. The baseline glenoid morphology, the glenoid wear rate, the proximal humeral head migration and implant overstuffing were evaluated radiologically in all patients. The radiological parameters were correlated with the functional outcomes.
resultsThe Constant-Murley score, the ASES score, and the OSS score were significantly better for patients with a concentric baseline glenoid compared to those with an eccentric glenoid. The Constant-Murley score and the ASES score were also improved in patients without implant overstuffing compared to patients with implant overstuffing (p < 0.05). However, glenoid wear was not associated with worse functional outcomes (p = 0.23 for Constant-Murley score, p = 0.15 for ASES score and p = 0.27 for OSS score). Last, a worse Constant-Murley score was strongly correlated with proximal humeral head migration (p < 0.001), while worse ASES and OSS scores were moderately correlated with proximal humeral head migration (p < 0.001).
conclusionOur findings indicate that the results of hemiarthroplasty can be improved through careful selection of patients upon the baseline glenoid type morphology and proper implant sizing to avoid implant overstuffing. Moreover, glenoid wear is not associated with worse clinical outcomes, therefore shoulder hemiarthroplasty should be reconsidered as an alternative in younger patients with shoulder arthritis.
