Application of real-time shear wave elastography technology in healthy pediatric hip joints.
Article in BMC medical imaging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRecently, pediatric hip joint diseases have received increasing attention, however, most researches focus on conventional ultrasound. The aim of our study is to explore the application of real-time shear wave elastography (SWE) technology in different tissue structures of healthy pediatric hip joints to distinguish between the normal and pathological states, and provide a normal reference range for shear wave Young's moduli for clinical practices and subsequent scientific researches.
methodsAccording to the selection criteria, 189 healthy full-term infants with 378 hip joints were enrolled, including 102 males and 87 females aged 2-90 days. They were divided into three groups based on age: 0-30 days (61 patients), 31-60 days (63 patients), and 61-90 days (65 patients). All the subjects underwent routine ultrasound examination to perform Graf typing, and then subjected to the SWE. The Young's moduli of the femoral head, acetabular lip, acetabular cartilage apex, gluteus medius, gluteus minimus, and iliacus were recorded. The differences in various parts among the three groups, between the left and right sides, and between males and females were compared. The 95% medical reference value range for each part was obtained and consistency test was conducted.
resultsThere was no statistically significant difference in various parts between the left and right hip joints (P > 0.05) or between males and females (P > 0.05). There were significant differences in the femoral head, acetabular lip, and acetabular cartilage apex among the three groups (P < 0.05). The Young's moduli of the femoral head, acetabular lip, and acetabular cartilage apex were positively correlated with age (r
conclusionReal-time SWE technology can be used to obtain the Young's moduli of healthy pediatric hip joints and surrounding tissues, and distinguish between healthy and pathological states. This can provide a normal reference range for shear wave Young's moduli for clinical practices and subsequent scientific researches.
