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
purposeTo compare re-rupture rates and clinical outcomes between bone-patellar tendon-bone (BTB) and hamstring tendon (HT) grafts in anterior cruciate ligament (ACL) reconstruction according to patient risk levels.
methodsThis retrospective cohort study included patients who underwent primary ACL reconstruction at a single institution between 2018 and 2022, with outcomes assessed at a fixed 2-year postoperative follow-up. The primary endpoint was graft re-rupture, defined as a traumatic graft failure confirmed clinically and by magnetic resonance imaging, and the secondary endpoint was the Knee injury and Osteoarthritis Outcome Score (KOOS). High-risk status was defined as the presence of all three risk factors: age ≤ 20 years, posterior tibial slope. (PTS) ≥ 12°, and participation in pivoting sports. For patients with two or fewer risk factors, propensity score matching was performed using age, sex, body weight, generalized joint laxity, knee hyperextension, participation in pivoting sports, and PTS as covariates to compare outcomes between BTB and HT grafts.
resultsIn the high-risk group, the BTB graft showed a significantly lower re-rupture rate compared to the HT graft (12.9% vs. 35.7%, p = 0.03), with no significant difference in KOOS overall score (96.3 ± 3.7 vs. 96.6 ± 6.3, p = 0.85). In the lower-risk group after matching, the BTB graft showed a similar re-rupture rate compared to the HT graft (6.9% vs. 5.2%, p = 0.99), with no significant difference in KOOS overall score (92.6 ± 6.9 vs. 94.8 ± 5.7, p = 0.10).
conclusionBTB grafts reduced re-rupture rates compared to HT grafts in high-risk ACL reconstruction patients, while clinical outcomes were similar. In lower-risk patients, no significant differences were observed between graft types in either re-rupture rates or KOOS overall score. LEVEL OF EVIDENCE: Level III.
