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: The purpose of this study was to compare revision rates, knee stability and patient-reported outcomes in a national cohort of anterior cruciate ligament (ACL) reconstructed patients using either the semitendinosus/gracilis (ST/G) or the 4-strand semitendinosus (4-ST) grafts. Methods: ACL reconstructed patients operated from 2015 to 2021 who met the following criteria: minimum 2-year follow-up and isolated ACL with either ST/G or 4-ST grafts. The primary outcome was ACL revision surgery assessed at 2-year follow-up. Secondary outcomes were knee laxity (side-to-side difference) and pivot shift (rotational stability difference-Grade 0 or Grade 1-3), and patient-reported outcomes; Knee Osteoarthritis and Outcome Score (KOOS) subscales and Tegner activity scale assessed at 1-year follow-up. Results: A total of 6750 ST/G and 1321 4-ST patients were included in the study. There was no statistical difference in 2-year revision rates between the groups (ST/G; 1.73 (95% confidence interval [CI] 1.44-2.07), 4-ST; 1.40 (95%CI 0.88-2.21)). A small significant but not clinically relevant difference was seen in knee laxity (1.27 mm vs. 1.13 mm), but no other significant differences were seen in pivot shift or patient-reported outcomes at one year. Both groups showed significant improvement from baseline to 1 year. Conclusion: The present study found no difference between ST/G or 4-ST in ACL reconstruction patients regarding revision rates, knee laxity and patient-reported outcomes. Level of Evidence: Level III.
