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: Glenoid bone loss is commonly encountered at the time of revision reverse shoulder arthroplasty (rTSA). The ipsilateral distal clavicle has been considered as one possible source of autograft if needed at the time of revision rTSA. The purpose of this study was to determine the outcome of ipsilateral distal clavicle autograft (IDCA) at the time of revision rTSA with particular attention to survival of the glenoid baseplate. Methods: Between 2017 and 2023, 20 consecutive revision rTSAs were performed at a single institution using IDCA augmentation of glenoid defects. The mean age at the time of surgery was 74 ± 12 years. Failed prostheses revised included 13 anatomic total shoulder arthroplasties and 7 failed rTSAs. According to the Kocsis classification, pre-operative bone loss was considered stage 2 in 12 shoulders and stage 3 in 8 shoulders. Intraoperatively, 15 patients had central bone defects and 5 patients had combined bone loss using Antuña classification. Clinical assessment was performed pre-operatively and post-operatively for pain, subjective, and objective scores. Radiographic evaluation analyzed the position of the glenoid component as well as radiographic evidence of graft incorporation and loosening. The mean follow-up time was 44 ± 12 months. Results: Mean visual analog scale scores for pain decreased 7 pre-operatively to 1 at most recent follow-up ( Conclusion: At mid-term follow-up, IDCA provided a reliable option for moderate glenoid bone loss encountered at the time of revision rTSA. A major benefit of IDCA is availability from the same surgical site of the revision procedure, even if pre-operative assessment underestimated bone loss. These results need to be confirmed in a larger sample size and with longer follow-up.
