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

The primary purpose of this study was to determine the preoperative predictors of gait biomechanics 6 months after unilateral total knee arthroplasty (TKA). There were 126 participants (age 64.4 ± 7.1 years, 75 females) who underwent instrumented biomechanical assessments while walking at a self-selected pace preoperatively, 10 weeks after (post-rehabilitation), and 6 months after unilateral TKA. Outcomes were peak knee extension moment (pKEM), knee angle excursion, and vertical ground reaction force (vGRF) ratio (surgical/contralateral). Potential clinical, demographic, and biomechanical predictors were tested univariately and considered a candidate for the final model if p < 0.15. Each multivariate model initially contained all candidates, and backward selection was used to determine the final model. Greater 6-month surgical limb pKEM was predicted (r
