Diagnostic Efficiency of MRI in Child and Adolescent Lateral Discoid Meniscus.
Article in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveIn the field of diagnosing the adult discoid lateral meniscus (DLM), MRI has undergone extensive research. However, the use of MRI for diagnosing DLM in children and adolescents remains controversial. This study aimed to explore the diagnostic efficiency of MRI for DLM in children and adolescents and to determine the diagnostic value of these indicators.
methodsThis retrospective study included children (aged between 4 and 11 years) and adolescents (aged between 12 and 17 years) from September 1, 2019 to January 1, 2023, who were diagnosed with lateral meniscus (LM) or DLM injury through arthroscopic surgery. All patients underwent a 3 T MRI examination before surgery. The MRI indicators included the LM width (LMW), ratio of the LMW to the tibia (RMT), percent coverage of the meniscus (PCM), tibial width (TW), height of the medial tibial spine (HMTS), height of the lateral tibial spine (HLTS), tibial eminence width (TEW), lateral slope angle of the medial tibial eminence (LSAMTE), lateral slope angle of the lateral tibial eminence (LSALTE), and presence of three "bow tie signs." A diagnostic efficacy analysis of all indicators was conducted to determine characteristic MRI diagnostic indicators and analyze their diagnostic value. Pearson's correlation analysis was conducted to evaluate the correlation between diagnostic indicators and baseline information.
resultsThis study included 90 patients (26 with LM injuries and 64 with DLM injuries). The average age was 12.81 ± 4.34 years, height was 151.24 ± 23.82 cm, weight was 48.20 ± 21.82 kg, and BMI was 19.69 ± 4.22 kg/m
conclusionThe MRI diagnosis of DLM in children and adolescents can be based on LMW, RMT, PCM, LSAMTE, and "bow-tie signs," with these indicators demonstrating good diagnostic efficacy.
