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
Introduction: Graft selection remains a critical determinant of outcomes in anterior cruciate ligament (ACL) reconstruction. While hamstring tendon (HT) autografts are widely used, variable graft diameter and knee-flexor morbidity remain concerns. The peroneus longus tendon (PLT) has emerged as a promising alternative offering predictable diameter and minimal donor-site morbidity. This study compares operative, functional, and stability outcomes between HT and PLT autografts in single-bundle arthroscopic ACL reconstruction. Materials and Methods: A prospective comparative study was conducted on 50 patients who underwent arthroscopic single-bundle ACL reconstruction at a tertiary care center. Patients were divided into two groups: Group A (n = 26) received quadrupled HT autografts, and Group B (n = 24) underwent reconstruction using PLT autografts. Outcome measures included operative duration, graft diameter, Lysholm and International Knee Documentation Committee (IKDC) scores (pre-operative, 6 months, 12 months, and 24 months), range of motion at 3 months, return to daily activities, return to sport activity, anterior knee laxity at 12 months by KT-1000 arthrometer, donor-site morbidity, graft failure, post-operative infection and overall functional outcome. Statistical analysis was performed using independent t-tests and Chi-square tests. P < 0.05 was considered statistically significant. Results: The peroneus longus group demonstrated significantly shorter operative duration (74.85 ± 5.13 vs. 89.20 ± 4.49 min; P < 0.001), larger graft diameter (8.39 ± 0.23 vs. 7.65 ± 0.34 mm; P < 0.001), superior Lysholm scores at 24 months (96.50 ± 2.09 vs. 90.15 ± 3.18; P < 0.001), better IKDC scores at 24 months (95.80 ± 2.67 vs. 89.10± 3.09; P < 0.001), improved early range of motion (128.55 ± 4.36° vs. 124.54 ± 3.93°; P = 0.013), earlier return to daily activities (9.07 ± 0.72 vs. 10.94 ± 0.97 weeks; P < 0.001), and earlier return to sports activity (193.1 vs. 229.6 days; P < 0.001). Moreover, lower anterior knee laxity (2.28 ± 0.26 vs. 2.94 ± 0.41 mm; P < 0.001). A significant positive correlation was identified between anterior knee laxity and delayed return to daily activities (r = 0.552, P = 0.002). Conclusion: PLT demonstrated favorable functional and operative outcomes and may represent an effective alternative to hamstring autograft in ACL reconstruction with respect to operative efficiency, graft diameter, functional recovery, and knee stability. PLT represents a safe and effective alternative graft, particularly in patients where adequate graft size and preservation of knee-flexor strength are desired.
