Age dependent morphological changes of the normal meniscus in children based on large scale MRI analysis.

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
To systematically quantify the morphological characteristics of normal meniscus in children and establish age-specific reference data to support accurate diagnosis and surgical decision-making for pediatric meniscal disorders. This retrospective study analyzed knee images of 877 children who underwent 3.0T plain magnetic resonance imaging (MRI) scans. The researchers categorized participants into four age groups: Group A (≤ 5 years), Group B (5 < age ≤ 10 years), Group C (10 < age ≤ 15 years), and Group D (15 < age ≤ 18 years) and randomly selected fifty children from each group for detailed morphological analysis. Measurements on coronal images included the width and thickness of the meniscal body, the width and height of the tibial intercondylar ridge, and the width of the tibial plateau. Measurements on sagittal images assessed the width and thickness of the anterior and posterior meniscal horns, along with the sagittal diameter of the meniscus. Morphological parameters across the four age groups were compared to evaluate developmental trends. This study collected and analyzed the morphological parameters of the normal meniscus in children across four age groups, including measurements of the anterior horn, body, and posterior horn, as well as the tibial plateau and tibial intercondylar ridge. The results showed that, except for the lateral meniscal anterior horn thickness (P = 0.223), nearly all measurements in Group B were significantly greater than those in Group A (P < 0.05). Similarly, most parameters in Group C were higher than those in Group B, except tibial intercondylar ridge width, which showed no significant difference (P = 0.988). When comparing Group C and Group D, most measurements showed no significant difference (P > 0.05); however, specific parameters were unexpectedly greater in Group C than in Group D, including the lateral meniscal anterior horn width, medial meniscal anterior horn width, medial meniscal body width, and medial meniscal posterior horn width (P < 0.05).In children aged 0 to 15 years, the meniscus demonstrates a progressive increase in size, reflecting normal growth and development. However, after age 15, this growth plateaus, and certain regions of the meniscus exhibit a slight reduction in size.
