More specifically, the mean CA of male subjects was 10.33 ± 4.44 years (SE = 0.73), and the mean SA was 9.57 ± 4.90 years (SE = 0.80), and the difference between the CA and SA for males was 0.75 years or 9.03 months with a highly significant p-value of 0.005 (SE = 0.25, t = 2.98 (df = 36), p ≤ 0.05), whereas the mean CA of female subjects was 11.50 ± 4.82 years (SE = 0.83), and the mean SA was 11.14 ± 4.68 (SE = 0.81), and the difference between the CA and SA for females was 0.36 years or 4.33 months with a significant p-value of 0.05 (SE = 0.18, t = 2.00 (df = 32), p ≤ 0.05) as shown in Table 1 .
