Scatterplot showing the relationship between AgeP50
and MathSelect values. The confidence interval (CI) for age at 50% of the pubertal growth function (AgeP50
) is related to the MathSelect cumulative probabilities generated for girls (red circles) and boys (blue crosses) in the study population. The computed MathSelect value is giving the expected percentage of a reference group with visually inspected acceptable growth curves having a higher quality than the actual fitted curve.
