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
introductionTo evaluate the structural and functional relationship between medial meniscus posterior root tear (MMPRT) and anterior cruciate ligament (ACL), the aim was to assess the structure and elasticity of the ACL in patients with MMPRT and to measure tibial anterior translation. MATERIALS AND
methodsBetween January and June 2024, 56 patients (study group) were diagnosed with unilateral MMPRT on magnetic resonance imaging (MRI) and 31 healthy volunteers (control group) were included in the study. While the tibial anterior translation of the patients was evaluated using the KT 1000 device, the structure and stiffness of the ACL were assessed with ultrasound shear wave elastography (SWE). The tibial slope measurement was taken at 30 degrees of knee flexion on true lateral radiographs where the femoral condyles overlapped.
resultsA total of 87 participants were included in the study, consisting of 31 volunteers (25 females, 6 males) and 56 patients diagnosed with MMPRT (48 females, 8 males). The average SWE values of the ACL were compared between the study group (26.6 ± 8.9 kPa) and the control group (21.2 ± 5.7 kPa), with the study group demonstrating a significantly higher value (p: 0.004). In patients with MMPRT, the measurements of anterior translation using the KT 1000 device were an average of 6.19 ± 1.4 mm in the affected knees and 4.9 ± 0.78 mm in the unaffected knees. The comparison revealed a significantly greater anterior translation in the knees with MMPRT (p < 0.05). Multivariable regression analysis demonstrated a significant positive relationship between ACL SWE values and tibial slope (β = 1.11; CI, 0.24-1.99; P: 0.01).
conclusionsGreater tibial anterior translation was observed on the side with MMPRT in the patients. There is a correlation between MMPRT and the stiffness of the ACL, which exhibits a higher elastic modulus. Additionally, an increase in tibial slope significantly affects the stiffness of the ACL. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
