Is there a directional relationship between windswept hips and scoliosis in children with cerebral palsy?

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.

Abstract
backgroundThe purpose of this study was to analyse if there is a relationship between the directions of windswept hip deformity and scoliosis for children with cerebral palsy (CP) and to explore potential associations with spasticity, contractures and hip displacement.
methodsA cross-sectional registry-based study was conducted using data from the combined Swedish CP Follow-up Program and National Registry, including children aged 0–18 years across all levels of the Gross Motor Function Classification System. Prevalence and direction of windswept hip deformity was assessed based on calculations of passive range of motion in abduction, internal and external rotation of the hips. Scoliosis was defined as either a moderate or severe curve at clinical examination or a radiographic Cobb-angel of ≥ 20°. The direction of scoliosis was determined by the convexity of the spinal curve.
resultsA total of 4,453 children (mean age 10.2 years [SD 4.8]) were included. In total 774 (17.4%) had scoliosis (n = 503) or windswept hips (n = 413). Among these141 had both scoliosis and windswept hips allowing for analyses of directional relationships. The scoliosis and windswept hip deformity were going in opposite directions in 75 of the 141 children, and in the same direction in 66 children. More children with scoliosis and windswept hips to the same side had a contralateral hip displacement (p < 0.001). Whereas children with deformities in opposite directions more frequently had a hip displacement contralateral to the windswept hip deformity. The direction of the scoliosis was associated with a contralateral hip displacement (p = 0.020). The direction of the windswept hip deformity was associated with a contralateral hip displacement (p < 0.001), hip flexion contracture (p = 0.002) and spasticity in the hip adductors on the opposite side (p < 0.001).
conclusionsThere is no clear directional relationship between windswept hips and scoliosis in children with CP. However, the direction seems to be highly associated with the location of hip displacement, hip flexion contracture and spasticity of the hip adductors. These findings suggest that preventing and treating contractures in the lower extremities, along with active hip surveillance, may help reduce the development of both scoliosis and windswept hip deformity.
