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: Literature focusing on reverse shoulder arthroplasty (RSA) for complex proximal humerus fractures (PHFs) in patients aged ≥ 80 years is limited. This study aimed to evaluate clinical and radiological outcomes of RSA and tuberosity fixation for complex four-part PHFs in elderly patients, with a minimum follow-up (FU) of 24 months. The secondary aim was to assess tuberosities healing rate and correlate it with clinical outcomes. Materials and methods: We retrospectively analyzed 26 patients (8 males, 18 females; mean age 84.6 years) who underwent cementless RSA for four-part PHFs. At the final FU, Constant-Murley score (CS), a 3-grade satisfaction scale and VAS scale were recorded. Radiological healing of greater (GT) and lesser tuberosity (LT) was also evaluated. Results: At a mean FU of 38 months, the mean CS was 61.30 ± 5.61 (range 38-76). Tuberosity healing occurred in 88% of patients. No significant difference ( Conclusions: RSA is a safe and effective treatment for complex four-part PHFs in patients over 80 years. The high tuberosity healing rate (88%) underlines the importance of fixation technique; however, tuberosity healing did not correlate with overall shoulder function but only with active external rotation. As for patients around 70 yrs, healing of LT was linked to GT healing, as isolated LT healing was never observed.
