Distribution of anterior inferior iliac spine morphology in patients with femoroacetabular impingement syndrome, developmental dysplasia of the hip, and asymptomatic controls: a retrospective cohort study.
Article in Skeletal radiology, 2026. 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
objectiveTo compare the distribution of anterior inferior iliac spine (AIIS) morphology on three-dimensional computed tomography (3D-CT) among hips with femoroacetabular impingement syndrome (FAIS), developmental dysplasia of the hip (DDH), and an asymptomatic control cohort. MATERIALS AND
methodsIn this single-center retrospective cross-sectional study, AIIS morphology was classified on 3D-CT using a four-subtype system. Asymptomatic control hips were selected from individuals undergoing abdominopelvic CT for non-orthopaedic indications, whereas FAIS and DDH hips were identified from patients evaluated for hip-preservation surgery. Lateral center-edge angle (LCEA) was measured on clinical anteroposterior pelvic radiographs or CT-derived anteroposterior digitally reconstructed radiographs, as applicable. AIIS morphology distributions were compared among groups using chi-square testing with post hoc pairwise analyses. Multivariable logistic regression was used to identify independent predictors of Type III morphology after adjustment for diagnostic group, LCEA, age, and sex.
resultsA total of 1,420 hips were analyzed, including 800 asymptomatic hips, 500 FAIS hips, and 120 DDH hips. AIIS morphology distribution did not differ significantly between the FAIS and asymptomatic cohorts. Type III morphology was identified in 9.2% and 9.3% of hips in these two groups, respectively. In contrast, the DDH cohort showed a significantly different distribution, with Type III morphology present in 60.0% of hips. On multivariable analysis, DDH remained the strongest independent predictor of Type III morphology (adjusted odds ratio, 7.99; 95% confidence interval, 3.33-19.14; P < 0.001).
conclusionStatic 3D-CT AIIS morphology did not distinguish FAIS hips from asymptomatic hips. In contrast, Type III morphology was markedly more common in DDH, suggesting that AIIS morphology should be interpreted in the context of acetabular coverage and the underlying hip disorder.
