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
Background: In patients undergoing medial open-wedge high tibial osteotomy (MOWHTO), the contralateral knee adduction moment (KAM) increases significantly postoperatively, indicating an increased risk of knee osteoarthritis. However, the factors associated with an increased KAM on the nonoperated side remain unexplored. Purpose: To identify the factors associated with KAM changes on the nonoperated side before and after MOWHTO. Study Design: Cohort study; Level of evidence, 2. Methods: Thirty participants scheduled to undergo MOWHTO were recruited between August 2020 and November 2022. Physical findings and knee alignment were assessed preoperatively and 1 to 2 years postoperatively with 3-dimensional gait analysis. Gait data were collected with a 3-dimensional motion analysis system and 2 force plates. Multiple regression analysis was performed to identify the factors associated with changes in the first and second KAM peaks on the nonoperated side after MOWHTO. Results: The hip adduction moment on the nonoperated side (standard partial regression coefficient [SPRC], 0.45; Conclusion: Changes in the first and second KAM peaks on the nonoperated side were significantly associated with surrounding alignment and joint moments during gait. In post-MOWHTO gait, controlling the knee adduction angle during the initial stance phase and contralateral pelvic drop during the terminal stance phase may be associated with a reduced risk of KOA development on the nonoperated side.
