1 · What the graph read from it

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.

2 · The registry

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

backgroundAtrophy of the gluteus medius and gluteus minimus has been reported in patients with developmental dysplasia of the hip (DDH). We aimed to investigate whether atrophy of the gluteus medius and gluteus minimus is associated with DDH.

methodsTwenty white New Zealand rabbits were divided into 2 groups in our experiment. In group 1, one limb of each rabbit was randomly selected for tenotomy of the gluteus medius and gluteus minimus, with the other side serving as a sham control. In group 2, one limb of each rabbit was randomly selected for intramuscular injection of botulinum toxin to induce atrophy of the gluteus medius and gluteus minimus, with the other side serving as a sham control by injection of equal volumes of normal saline. Acetabulum and muscles were evaluated by ultrasound, X-ray imaging, shear wave elastography, and histology with hematoxylin-eosin (H&E) staining.

resultsAtrophy of the gluteus medius and gluteus minimus was observed on the experimental side in both groups. Early dysplastic changes in the hips on the tenotomy side was observed on the radiographs with an increased acetabular index (40.0 ± 6.7° vs 24.1 ± 1.9°, P < 0.001) compared with the control side in group 1. No dislocation of the hips was observed. No dysplasia of the hips was observed on the botulinum-toxin side in group 2 with similar acetabular index on both sides (25.0 ± 3.7° vs 24.1 ± 1.9°, P = 0.13).

conclusionsTenotomy, not atrophy, of the gluteus medius and gluteus minimus is associated with early changes of DDH.
