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: Clinical evidence indicates that an unintended increase in the medial proximal tibial angle (MPTA) can occur during slope-reducing tibial osteotomies, which is most relevant in anterior cruciate ligament (ACL) deficient knees. Therefore, the purpose of this three-dimensional (3D) simulation study is to assess how axial or coronal hinge axis rotation affect alignment parameters in anterior tibial closing wedge osteotomies (ACWO). The hypothesis states that a neutral hinge axis (NHA) in ACWO prevents changes in coronal and axial alignment. Methods: A 3D surgical simulation was used to perform ACWO with a stepwise increment of one-degree (1°-5°) rotation around thirteen different hinge axes. Surface models were created from CT scans of 49 individuals (mean PTS 11.5° ± 3.8°) resulting in 3185 simulations. A NHA not changing the coronal or axial alignment was defined as oriented parallel to the posterior tibial plateau 1 cm underneath the articular surface. Anatomical landmarks were determined for each simulation to measure the PTS, MPTA, hip-knee-ankle angle (HKA), and tibial torsion (TT). The effects of the initial MPTA or PTS on the resulting alignment parameters and the effects of axial and sagittal rotation of the joint axis were analysed for their effects on postsimulation PTS, MPTA and TT. Results: Clinically relevant hinge axis rotation in the coronal or axial plane below 20° did not significantly influence PTS correction ( Conclusion: NHA aligned parallel to the posterior tibial plateau below the articular surface prevents significant changes in MPTA during ATCWO. This 3D simulation suggest, that hinge axis orientation requires meticulous consideration during slope-reducing osteotomies to preserve alignment integrity. Level of Evidence: Level V, retrospective simulation study.
