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) for proximal humerus fractures is becoming more common. The aim of this study was to investigate the radiographic outcomes of uncemented rTSA for proximal humerus fractures and compare these outcomes based on 3 different implants. Methods: This was a retrospective review of patients treated with uncemented primary rTSA for acute proximal humerus fracture at 2 large healthcare institutions using one of 3 different humeral stem designs. Group A (n = 46) received a Zimmer TM stem, group B (n = 27) received a DJO Altivate stem, and group C (n = 18) received a Medacta stem for a total of 159 patients. Three independent reviewers assessed the most recent x-rays for 1) humeral subsidence, 2) humeral tilt, 3) humeral radiolucent lines, 4) humeral stem at risk for loosening, 5) osteolysis, 6) humeral stress shielding, 7) component failure, 8) spot welds, 9) scapular notching, and 10) tuberosity union. Results: The mean follow-up was 21 months (range, 6 months to 10 years). The average age at the time of surgery was 71.0 years old. Radiographic analysis showed group C (67%) was associated with significantly higher rates of stress shielding compared to group B (19%) and group A (6.5%) ( Conclusion: Overall, we found significant variability in radiographic performance, particularly regarding stress shielding and risk of stem loosening when evaluating radiographic outcomes of these 3 cementless humeral stem designs used in rTSA for proximal humerus fractures.
