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 the key factors influencing post-operative range of motion after total knee arthroplasty. The primary determinants investigated were preoperative range of motion, intra-operative posterior condylar offset (PCO), posterior condylar offset ratio (PCOR), posterior tibial slope (PTS), and joint line height (JLH). Methods: This prospective study enrolled 68 patients. PCO, PCOR, PTS, and JLH were assessed radiologically in both pre-operative and post-operative X-rays. The knee range of motion and Oxford Knee Score (OKS) were assessed at 2-year follow-up. Statistical analysis, including Student's t test and correlation analysis, was employed to compare and correlate pre-operative and post-operative parameters. Results: Pre-operative range of motion correlated with post-operative range of motion ( Conclusion: Amongst the measured parameters, pre-operative range of motion was the primary factor influencing the range of motion attained after total knee arthroplasty (TKA).
