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
backgroundIn tibial plateau fractures, achieving anatomical restoration of the articular surface and preventing postoperative collapse are critical for successful outcomes. Bone grafting is still commonly used to fill subchondral voids after reduction; however, it carries risks such as donor-site morbidity and technical difficulties. To address these issues and enhance subchondral stability, sub-chondral raft techniques have been developed. Although various screw and plate configurations have been investigated in the litera-ture, there is still no clear consensus regarding the most effective method. We aimed to evaluate the effectiveness of our modified technique using free 5.5-mm cannulated compression screws in preventing postoperative collapse and improving functional recovery in tibial plateau fractures.
methodsA total of 21 patients were included based on the following criteria: age ≥18 years, presence of >10 mm depression in the lateral tibial plateau, and no history of previous surgery on the affected knee. A subchondral raft construct was established without grafting using free 5.5-mm cannulated compression screws. Postoperative evaluation at 12 months included radiological and functional assessments using the Rasmussen Clinical Score (RCS) and Rasmussen Radiological Score (RRS).
resultsThe mean preoperative articular depression was 14.7 mm, improving to 1.1 mm at the one-year follow-up. Mean condylar widening decreased from 5.3 mm preoperatively to 0.7 mm postoperatively. The average postoperative hospital stay was 3.7 days, and the mean time to return to work was 3.5 months. At one year, radiological and functional outcomes were favorable, with a mean RCS of 26.6 and a mean RRS of 16.6.
conclusionThe modified raft technique using 5.5-mm cannulated compression screws is a simple and effective option for managing depressed tibial plateau fractures, preventing articular collapse and facilitating faster recovery.
