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

Purpose: This study aimed to identify risk factors associated with deterioration in knee flexion range of motion (ROM) following cruciate-retaining total knee arthroplasty (CR-TKA). Methods: A total of 129 consecutive patients who underwent CR-TKA and completed a 2-year follow-up were included. A decrease of ≥9° in flexion ROM was considered clinically significant. Patients were classified into two groups based on the change in flexion ROM at 2 years post-operatively: Group D (≥9° decrease; Results: Demographic characteristics were comparable between the two groups. Preoperative flexion ROM was significantly higher in Group D than in Group C (128.6 ± 9.5° vs. 115.5 ± 12.3°, Conclusions: Preoperative flexion ROM, DMFR and 1y30AP were associated with worse flexion ROM at 2 years following CR-TKA. Level of Evidence: Level III, retrospective comparative study.
