1 · What the graph read from it

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.

2 · The registry

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: Reverse total shoulder arthroplasty (RTSA) is an increasingly popular salvage treatment option for proximal humeral fracture (PHF) sequelae. This meta-analysis aimed to conduct a pooled analysis of functional outcomes of RTSA in PHF sequelae, with subgroup analysis comparing between intracapsular (Class 1) and extracapsular (Class 2) PHF sequelae. Methods: A multi-database search (PubMed, OVID, EMBASE) was performed according to PRISMA guidelines on 27th July 2020. Data from all published literature meeting inclusion criteria were extracted and analysed. Findings: Eleven studies were included, comprising 359 shoulders (167 Class 1 and 192 Class 2). The mean age was 68.2 years, and the mean time between injury and surgery was 49 months, (1-516 months). Constant score and forward flexion improved by 31.8 (95%CI: 30.5-33.1, p < 0.001) and 60o (95%CI: 58o-62o, p < 0.001) respectively between pre-operative and post-operative values for both groups. Constant scores were better in Class 1 patients (MD = 3.60, 95%CI: 1.0-6.2, p < 0.001) pre-operatively and post-operatively (MD = 7.4, 95%CI: 5.8-9.0, p < 0.001). Forward flexion was significantly better in Class 1 patients (MD = 13o, 95%CI: 7o-17o, p < 0.001) pre-operatively, but was slightly better in Class 2 patients post-operatively (MD = 7o, 95%CI: 4o-10o, p < 0.001). Overall complication rate was 16.8%. Conclusion: Salvage RTSA is effective for PHF sequelae, with multiple factors contributing to the high complication rate.
