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: Conventional techniques (medial collateral ligament + posterior oblique ligament reconstructions), such as those by Lind and LaPrade, do not fully restore native knee stability in severe medial injuries. This study aimed to determine the optimal tibial insertion site for an anteromedial (AM) reconstruction strand mimicking the deep medial collateral ligament (dMCL), to better control anteromedial rotatory instability (AMRI) in knees with complete medial injury (sMCL + dMCL + POL). Methods: Twenty fresh-frozen cadaveric knees (13 female, 7 male donors; mean age: 80 years) were tested using Dyneelax® static laximeter at 30° of flexion. After standardised transections of the superficial MCL (sMCL), deep MCL (dMCL), and posterior oblique ligament (POL), each knee was reconstructed using a trifid flat graft including an AM strand. Knees were assigned to two groups based on the tibial insertion angle (α) between the AM strand and the sMCL: group Results: Both reconstruction techniques significantly reduced laxity compared to the transected state. However, group Conclusion: There is a trend toward better stability with a more oblique AM strand, which must be confirmed by further biomechanical studies. This trifid flat graft approach more accurately replicates the biomechanical function of the dMCL and anteromedial capsule, and could provide a refined strategy for reconstructing severe medial knee instability. Level of Evidence: Level V, experimental cadaveric study.
