Figure 1 Z score of combined kidney volume (cm3) from 0 to 18 months of age. (A) Children born at term (gestational age 37 to 42 weeks stratified into six categories of weight for gestational age. Symbols are: (•) 0 to 9.9 percentile (N = 80); (▾) 10 to 24.9 percentile (N = 135); (○) 25 to 49.9 percentile (N = 182); (▴) 50 to 74.9 percentile (N = 186); (□) 75 to 89.9 percentile (N = 107); (▵) 90 to 100 percentile (N = 92). (B) Children born approximately for gestational age (weight for gestational age ± 2 SD) stratified into three categories according to maturity (preterm, term, and postterm). Symbols are: (•) <37 weeks of gestation (N = 58); (□) 37 to 42 weeks of gestation (N = 717); (▵) >42 weeks of gestation (N = 46). Dots represent means (± SEM).
