Longitudinal bone ages of boys (a) and girls (b) with Progeria, estimated via the method of Greulich and Pyle [14]. The graphs showed that 85/113 (75%) estimated bone ages for boys and 90/120 (75%) estimated bone ages for girls fell within ±2 standard deviation of normal (gray shaded region). Of note, for the calculation of the number of bone ages falling within ±2 standard deviation of normal, the normal gray shaded region was extrapolated to adulthood (i.e. beyond the provided age limits of 17-year-old for boys and 16-year-old for girls).
