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

objectivesThe aim of this study was to identify threshold values in the pre- and post-operative Oxford knee score (OKS), and change in the score for differing levels of patient satisfaction with their total knee replacement (TKR).

methodsWe prospectively collected pre-operative and 1-year post-operative OKS for 2392 patients undergoing a TKR. Patient satisfaction was categorically assessed, according to whether they were: very satisfied, satisfied, neutral, and unsatisfied. Receiver operating characteristic curve analysis was used to identify thresholds in the OKS score that identified each level of patient satisfaction.

resultsThe post-operative OKS was the most accurate predictor of the level of patient satisfaction (area under the curve = 0.86). Very satisfied patients had a threshold value in the post-operative OKS of ≥36, which decreased to ≥27 points for satisfied patients, and further still to ≤25 for unsatisfied patients.

conclusionThe threshold values, we have identified for the different levels of satisfaction using the post-operative OKS, which is the most accurate predictor, can be used to predict level of patient satisfaction and give quantification of the OKS.
