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

introductionIn cases of limited medical resources, elective total knee arthroplasty (TKA) sometimes needs to be performed after typical work hours. However, surgeon fatigue and logistical factors may potentially affect outcomes. This study aimed to detect whether after-hour procedures impair outcomes after TKA. MATERIALS AND

methodsElective unilateral TKA from Jan 1, 2016 to Nov 31, 2018 was retrospectively selected and separated into two groups. Procedures started from 8:00 A.M. to 5:29 P.M. were identified as day-time surgeries, whereas those started from 5:30 P.M. to 11:59 P.M. were considered after-hour surgeries. Operative period, Knee Society Score (KSS), range of motion (ROM), total blood loss, length of hospital stay (LOS), and postoperative adverse events and complications were compared. Additionally, the components were evaluated radiologically.

resultsA total of 321 patients were selected, including 258 (80.37%) patients in the day-time group and 63 (19.63%) patients in the after-hour group. Operative period, LOS, total blood loss were similar between groups. The overall and each specific incidence of postoperative complications were comparable between the two groups, but the incidence of postoperative vomiting (POV) was higher in the after-hour group. There was no significant difference in knee joint function as shown by the KSS and ROM, both on the 3rd day and at 2 years after surgeries. Radiologically, there were no significant differences between the two groups in the femoral notches (P = 0.592). However, better coronal alignment was detected in the day-time group (P = 0.002), consistent with which there were less outliers (P = 0.033).

conclusionAfter-hour TKA procedure does not exert an impact on clinical outcomes, but negatively affects lower limb alignment. Besides, after-hour TKA surgery impairs patients' comfort by increasing POV.
