Data are mean ± SD. aP < 0.05 for the comparison with the shortest quartile of height by using analysis of covariance and Dunnett's test for post hoc analysis. bP values for trend were performed by assigning the median values of each quartile of height and fitting this as a continuous variable in a separate regression model.
