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 clinical outcomes of locking plate versus cancellous screw fixation in structural autologous bone grafting for medial tibial bone defects during total knee arthroplasty. Methods: A retrospective analysis was conducted on 66 patients with medial tibial bone defects who underwent TKA between January 2024 and December 2024. Among them, 34 patients received locking plate fixation (LP group), and 32 patients received cancellous screw fixation (CS group). Postoperative outcomes, including the hip-knee-ankle (HKA), Knee Society Score (KSS) and postoperative complications were recorded and compared to evaluate graft integration and functional recovery. Results: All patients successfully completed the surgery. At the final follow-up, both groups showed significant improvement in HKA angle, KSS Knee Score, and KSS Function Score compared to preoperative values (P < 0.05). However, no statistically significant differences were observed between the two groups at any time point in terms of KSS Knee and Function Scores (P > 0.05). No postoperative complications occurred in either group during the follow-up period. Conclusion: Compared with conventional cancellous screw fixation, the use of locking plate combined with structural autologous bone grafting provides similarly favorable clinical outcomes. Furthermore, locking plate offer broader intraoperative applicability and may serve as an effective internal fixation strategy for managing medial tibial bone defects during TKA.
