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

backgroundPreoperative psychological distress may be related to dissatisfaction and poorer outcomes after total knee arthroplasty (TKA). However, the kind of psychological distress that could influence postoperative satisfaction and outcomes remains controversial. Few studies have examined these issues in Chinese cohorts. Thus, this study aimed to examine (1) the prevalence of preoperative psychological distress in patients undergoing TKA and (2) whether preoperative psychological distress influences patient satisfaction, early postoperative outcomes, and improvement of knee function after TKA.

methodsWe prospectively included 210 patients undergoing unilateral primary TKA between March 2017 and September 2017 at our institution. Preoperatively, patients completed the Depression Anxiety and Stress Scales and new Knee Society Scores (KSS) questionnaires. At 3 months and 1 year postoperatively, patients' KSS and overall satisfaction were assessed. Stepwise multivariate linear regression models were used to assess the variables that influenced changes in each KSS item.

resultsPreoperatively, 89 (42.4%) patients experienced psychological distress. The satisfaction rate and postoperative KSS were not significantly different between patients with or without psychological distress; a higher preoperative score was shown to predict less KSS improvement. Patients with depression had fewer symptom score changes.

conclusionsThe prevalence of preoperative psychological distress was relatively high; thus, surgeons should consider the patient's psychological state. Patients' satisfaction was not influenced by psychological factors. Patients with depression and higher preoperative scores had lower symptom scores and KSS improvement, respectively.
