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

Although postoperative strokes after total hip arthroplasty are infrequent, they result in severe injury and can be fatal. This retrospective cohort study employed data from the nationwide research database. The study comprised 44,752 patients aged ≥ 40 years who received total hip arthroplasty from 2005 to 2017. The population were categorized into two groups based on the presence or absence of preoperative stroke. Patients with preoperative stroke exhibited a 4.37 times higher risk of postoperative stroke than did those without preoperative stroke (95% confidence interval [CI]: 1.82-10.48). Moreover, patients with preoperative stroke exhibited a 33.19 times higher risk of postoperative stroke when the elapsed time between preoperative stroke and surgery was less than 180 days (95% CI: 9.12-120.77). However, when the elapsed time was more than 365 days, the risk of postoperative stroke was only 2.25 times higher (95% CI: 0.69-7.32). Furthermore, patients with preoperative stroke had a 1.22 times higher risk of postoperative death (95% CI: 0.68-2.15), but this result is not statistically significant. In conclusion, delaying total hip arthroplasty for at least 1 year after stroke may lower the risk of postoperative stroke.
