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: We analysed the long-term revision rate, clinical outcomes and metal ion concentrations in blood over time in patients who had undergone metal-on-metal Articular Surface Replacement (ASR) hip arthroplasty. Methods: A total of 38 patients (43 hips) were included: 24 patients (28 hips) underwent large-head total hip arthroplasty (XL THA), and 14 patients (15 hips) underwent hip resurfacing arthroplasty (HRA). The median follow-up time was 11 (range 7-12) years. Results: None of 15 HRA implants were revised. Nine of 28 XL THA implants (32%) in 8 patients were revised. The Co ion levels significantly increased in the XL THA group (p=0.009) over a median time period of 84 (25-97) months. Conclusion: The levels of Co ions in blood were higher in the patients who had undergone XL THA and increased significantly over time.
