From: Novel type of references for weight aligned for onset of puberty – using the QEPS growth model
References in kg (left axis) and in kg0.5 (right axis) for total weight and the prepubertal/basic weight (weight gained independently of puberty (QES-function) for girls (red, left) and boys (blue, right). Curves are aligned for age at onset of pubertal growth spurt. Mean total weight (red/blue solid line, ±1SDS (red/blue dotted line), and ± 2SDS (red/blue dashed line) and mean basic weight (black). References shown in Fig. 2 upper panel with the addition of a puberty-specific weight reference showing weight gain resulting from the P-function of the QEPS (P weight). Specific P-function-derived weight as mean, ±1SDS (dotted line), and ± 2SDS (dashed line). The individual onset of puberty was identified and aligned based on the age at which 5% (AgeP5) of the total specific P-function growth (Pmax) had occurred
