†High: height or weight≥reference standard; low: height or weight<reference standard.
‡High: height or weight≥reference standard; low: height or weight<reference standard.
§The reference height and weight were used to calculate the BMI reference.
¶Male: high: BSA≥1.26 m2, low: BSA<1.26 m2; female: high: BSA≥1.22 m2, low: BSA<1.22 m2.
Mean of male BSA=1.26 m2; mean of female BSA=1.22 m2.
BMI, body mass index; BSA, body surface area.
