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

Objective: To compare the mid-term efficacy and cost-effectiveness of unicompartmental knee arthroplasty using a Mobile-Bearing and a Fixed-Bearing in elderly patients with knee osteoarthritis. Method: This study is a multicenter retrospective cohort study. 502 patients who underwent surgery at four joint centers from July 2020 to July 2023 were included and divided into a Mobile-Bearing Group ( Result: The surgical time of the Mobile-Bearing Group was longer than that of the Fixed-Bearing Group, and the difference was statistically significant (t = 8.524, Conclusion: Compared with Fixed-Bearing unicompartmental, Mobile-Bearing unicompartmental can provide better pain relief, functional recovery, and patient satisfaction in the mid-term, but it is accompanied by higher medical costs and specific complication risks; Fixed-Bearing unicompartmental is a more economical alternative.
