*
Determined by a birth weight below the 10th percentile for gestational age according to standards defined by a study group of the Health Ministry in Japan.
†
Calculated according to the formula recommended by the Japanese Society of Nephrology: eGFR (ml/min/1.73 m2)=194 × [Cre (mg/dl)]−1.094 × [Age (years)]−0.287 (×0.739 if the subject is a woman).
AGA, appropriate for gestational age; BMI, body mass index; eGFR, estimated glomerular filtration rate; ELBW, extremely low birth weight (<1000 g); HDL, high-density lipoprotein; LDL, low-density lipoprotein; SGA, small for gestational age.
Data are expressed as mean (SD) or number (%).
