Imaging study of pelvic morphology in adolescent idiopathic scoliosis: a retrospective study.
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeThis study aimed to examine pelvic morphology differences between adolescents with and without AIS, investigate variations among AIS patients with different scoliosis degrees and segments, and identify factors influencing pelvic rotation and tilt in relation to scoliosis.
methodsImaging data from 213 AIS patients and 187 normal adolescents were analyzed using the Caldwell-Moloy pelvic morphology classification. Differences in pelvic morphology were compared, and Cobb angle, vertebral rotation, pelvic rotation, and coronal pelvic tilt were measured and correlated.
resultsThe non-scoliotic group had the highest percentage of Gynecoid-type pelvises (35.3%) and the lowest Platypelloid-type pelvises (14.5%). The AIS group had the highest Gynecoid-type pelvises (52.6%) and the lowest Anthropoid-type pelvises (8.9%). Significant differences were found between the groups (P < 0.001). Pelvic morphology varied among AIS patients with different scoliosis degrees (P = 0.006) but not segments (P = 0.554). Cobb angle correlated with vertebral rotation (P < 0.001).
conclusionPelvic morphology significantly differs between AIS and non-scoliotic adolescents. These descriptive findings suggest a possible relationship between spinal deformity and pelvic structure. Further longitudinal or mechanistic studies are needed to determine whether pelvic morphology plays a role in AIS screening, progression monitoring, or treatment planning.
