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: Retrotuberosity biplane open-wedge high tibial osteotomy (RTOWHTO) Purpose: To compare the arthroscopically assessed femoral trochlear cartilage degeneration and radiographic patellofemoral-specific parameters after RTOWHTO, STOWHTO, and CWHTO. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 58 RTOWHTOs, 59 STOWHTOs, and 88 CWHTOs were examined using first-look arthroscopy between 2013 and 2022. The demographics did not differ significantly between the groups. Hardware removal and second-look arthroscopy were performed, on average, 29.7, 26.9, and 26.7 months after the RTOWHTOs, STOWHTOs, and CWHTOs, respectively ( Results: The prevalence rates of femoral trochlear cartilage degeneration were 17.2% (10/58), 39% (23/59), and 19.3% (17/88) in the RTOWHTO, STOWHTO, and CWHTO groups, respectively ( Conclusion: RTOWHTO may provide favorable patellofemoral joint outcomes, with a lower prevalence of trochlear cartilage degeneration and less lateral patellar translation than STOWHTO, as well as less patellar height lowering than both STOWHTO and CWHTO.
