Scatterplot showing relationship between; Ppubgain (left), QESpubgain (middle) and Tpubgain (right), related to AgeP50 in the upper panels, and related to Qmax in the lower panels. Upper left panel: Ppubgain as 95% of P max (the P-function of the total growth during puberty) is not related to AgeP50 (age at 50% of the P-function) for girls (red circles) and boys (blue crosses) in the study population. For girls; Ppubgain = 14.393–0.1850× AgeP50, adjusted r2 = 0.0019. For boys; Ppubgain = 15.243 + 0.0917 x AgeP50, adjusted r2 = −0.0002. Upper middle panel: QESpubgain in total height in cm during pubertal years, from 5% of the P-function (AgeP5) to 100% of P-function is related to AgeP50 (age at 50% of the P-function) for girls (red circles) and boys (blue crosses) in the study population. For girls; QESpubgain = 45.430–2.461xAgeP50; adjusted r2 = 0.769. For boys; QESpubgain = 42.899–2.080xAgeP50 adjusted r2 = 0.747. Upper right panel: Tpubgain, gain in total height in cm during the pubertal years, from 5% of the pubertal growth function (AgeP5) to 100% of the pubertal growth function (AgeP100), is related to AgeP50 (age at 50% of the P-function) for girls (red circles) and boys (blue crosses) in the study population. For girls; Tpubgain = 59.823–2.647× AgeP50, adjusted r2 = 0.395. For boys; Tpubgain = 58.142–1.988xAgeP50, adjusted r2 = 0.253. Lower left panel: Ppubgain as 95% of P max (the P-function of the total growth during puberty) is related to Q max (gain in adult height in cm due to Q-function growth) for girls (red circles) and boys (blue crosses) in the study population. For girls; Ppubgain = 38.704–0.272xQ max , adjusted r2 = 0.355. For boys; Ppubgain = 40.065–0.226xQ max , adjusted r2 = 0.277. Lower middle panel: QESpubgain in total height in cm during pubertal years, from 5% of the pubertal growth function (AgeP5) to 100% of the pubertal growth function (AgeP100), is related to Q max for girls (red circles) and boys (blue crosses) in the study population. For girls; QESpubgain = −2.797 + 0.189xQ max , adjusted r2 = 0.276. For boys; QESpubgain = −2.499 + 0.160xQ max , adjusted r2 = 0.303. Lower right panel: Tpubgain, gain in total height in cm during the pubertal years, from 5% of the pubertal growth function (AgeP5) to 100% of the pubertal growth function (AgeP100) versus Q max for girls (red circles) and boys (blue crosses) in the study population. For girls; Tpubgain = 35.906–0.0829× Q max , adjusted r2 = 0.0228. For boys; Tpubgain = 37.566–0.0666× Q max , adjusted r2 = 0.0187
