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.
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: The optimal management of the patella during total knee arthroplasty (TKA) has not been updated with the development of prosthesis. The purpose of this prospective randomised clinical trial was to compare the physical findings and patient-reported outcome measures between knees with patellar resurfacing and those without patellar resurfacing in the same patients undergoing simultaneous bilateral TKA using a contemporary zirconium ceramic femoral component. Methods: Forty patients (80 knees) scheduled for simultaneous bilateral primary TKA due to osteoarthritis received patellar resurfacing on one side knee indicated by randomisation (either left or right) and patellar non-resurfacing on the opposite side. A posterior-stabilised prosthesis with the contemporary zirconium ceramic patella-friendly femoral component (ACTIYAS Kyocera, Kyoto, Japan) was used with the measured resection technique with mechanical alignment in all cases. All patients were followed for a minimum of 2 years. Knee Society knee score and function score, the 2011 Knee Society score, numerical rating scale for pain, patient overall assessment of the knee (0 being "worst"-100 being "normal"), and symptom around the patella were compared between the two groups. Results: There were no significant differences in postoperative objective knee indicators, postoperative patient-reported outcome measures, and postoperative examination of the patellofemoral joint between the knees that received patellar resurfacing and patellar non-resurfacing, without baseline differences. Patient overall assessment of the knee averaged 86.3 in the patella resurfacing group while 84.2 in the non-resurfacing group ( Conclusion: Excellent physical findings and patient-reported outcome measures were observed following TKA with the contemporary zirconium ceramic femoral component, regardless of whether patellar resurfacing was performed, in the short term. Level of Evidence: Level II, lower quality randomised trials.
