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
Objective: To compare the safety and early effectiveness between conventional manual technique and domestic robot-assisted simultaneous bilateral medial unicompartmental knee arthroplasty (UKA). Methods: Clinical data of 59 patients who underwent simultaneous bilateral UKA and met the selection criteria between January 2023 and June 2024 were retrospectively analyzed. Among them, 30 patients received bilateral UKA via conventional surgery with Oxford mobile-bearing unicompartmental knee prosthesis (conventional group); another 29 patients underwent bilateral UKA with LINK SLED fixed-bearing unicompartmental knee prosthesis assisted by the domestic NATON robotic surgical system (robotic group). Baseline data including gender, age, body mass index, disease duration, Kellgren-Lawrence grade, and preoperative American Knee Society Score (KSS) and Oxford Knee Score (OKS) showed no significant intergroup differences ( Results: The conventional group had significantly shorter operation time than the robotic group ( Conclusion: Although robot-assisted simultaneous bilateral UKA requires longer operation time, it achieves comparable early effectiveness and safety to conventional manual simultaneous bilateral UKA, with superior accuracy of prosthesis implantation. The domestic robot-assisted system demonstrates promising clinical application value in simultaneous bilateral UKA.
