Geometric morphometrics of adolescent idiopathic scoliosis: a prospective observational study.
Observational study in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
objectiveAdolescent idiopathic scoliosis is the most prevalent type of scoliosis, and its consequences on the human torso have not been deeply studied. In spite of being a 3D condition, clinical management is circumscribed to 2D images among health-care professionals. GMM is a well-recognized tool in the study of 3D shape and symmetry.
methodsTwenty-four subjects with AIS and 24 controls were subjected to surface scan. Digitization and shape data were extracted and submitted to GMM analysis. 3D shape and asymmetry were correlated with Cobb angle in subjects with X-ray availability. Comparisons of mean shapes were done between each group and its symmetric average shape and between each group at two states: initial and 6 months after.
resultsAIS and controls show similar areas of asymmetry, being significantly higher in quantity in AIS (PD = 0.045; PD 0.037; p < 0.001). Significant correlation was observed between Cobb angle and Procrustes asymmetry (r = 0.38; p = 0.01) as happened with 3D shape (r = 0.11; p < 0.001). No significant changes were observed in the 3D shape of both groups 6 months after (AIS, p = 0.51; control, p = 0.304).
conclusionThe greater asymmetry observed in AIS was expectable, but the similarity of areas of asymmetry in both groups made us suspect of directional asymmetry in the human torso that could explain the high prevalence of right scoliosis observed in nature. The shape of the torso and the asymmetry should be considered as variables to study in AIS due to its correlation with Cobb angle. Progression of the deformities was not observed in our study, maybe due to short-term follow-up.
