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

We aimed to clarify the possibility of using bipolar hip arthroplasty (BHA) for degenerative diseases by examining long-term results postoperatively in 336 hips. Patients' average age was 61.0 years (range, 34-88 years), and the average follow-up period was 12.5 years (range, 5.0-27.3 years). The 5-year, 10-year, and 20-year Kaplan Meier survival rates (end point: revision) were 92.1%, 81.8%, and 20.1% in the osteoarthritis group and 96.4%, 90.1%, and 24.6% in the rheumatoid arthritis group, respectively. Since the survival rate for more than 10 years decreases rapidly, the use of BHA for treating degenerative diseases should be restricted.
