Menarche class probabilities are associated with measures of pubertal timing and status. a Density plot of post-menarche class probabilities of the pre- and post-menarche groups respectively. Class probability of 1 signifies a 100% confident classification as post-menarche, class probability of 0 signifies a 100% confident classification as pre-menarche. b Association of age at menarche and menarche class probability controlled for age and scanner. c Distribution of class probabilities (age- and scanner residualised) by puberty category (youth-reported)
