^ǂ The SH of AIS patients has been corrected by Bjure’s equation, and all the other analysis was carried out by the corrected height instead of measured height
ORs are per SD increase in height, weight, or body composition. Minimally adjusted ORs are adjusted for age. Fully adjusted ORs are additionally adjusted for standing height, fat mass and lean mass. Staticial significances were highlighted in bold
(In logistic regression, control is set as “0” and AIS is “1”)
