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: Tibial plateau fractures present a diagnostic challenge due to complex morphology and demanding anatomy. Reliable diagnosis is essential for treatment planning and clinical outcomes. Prior studies showed benefits of 3D computed tomography (3DCT) and 3D printing (3DP) using CT-based systems, but the potential of mixed reality (MR) remains unexplored. This study tested the hypothesis that MR enhances spatial understanding of fracture morphology, thereby improving interobserver reliability and diagnostic confidence across modern classification systems compared to CT, 3DCT and 3DP. Methods: Twenty-two intra-articular tibial plateau fractures (Arbeitsgemeinschaft Osteosynthese [AO]/OTA type B or C) were assessed using four visualisation modalities: (1) CT, (2) 3D reconstructions, (3) 3D-printed models and (4) MR holograms (Microsoft HoloLens 2). Twelve raters (six junior and six senior surgeons) classified each fracture using AO/OTA, 10-segment and revisited Schatzker systems and rated their diagnostic confidence using a 5-point Likert scale. Interobserver reliability was measured via kappa coefficients and percentage match. Differences were analysed using one-way analysis of variance ( Results: MR demonstrated the highest interobserver reliability for all classification systems: AO/OTA (0.43 vs. 0.32 for CT), 10-segment (0.17 vs. 0.11) and revisited Schatzker (0.43 vs. 0.24). Diagnostic confidence for AO/OTA differed significantly between modalities ( Conclusion: MR improved classification reliability and diagnostic confidence for tibial plateau fractures compared to CT, 3DCT and 3DP. The effect was most evident in less-experienced surgeons, indicating MR's value for surgical training and preoperative planning. Further research should explore MR's integration into education and its impact on clinical outcomes. Level of Evidence: Level II.
