Figure 2.

(A) The histogram of the difference (Δ) between estimated biological age BA_E from equations (1), (5), and (6) and CA; (B) BA_E estimated using equations (1), (5), and (6). (C) BA_EC estimated using equation (3) with w_CA corresponded to the $s_{\text{BC}}^2=150$. The histograms are overlaid with the normal curves with the parameter: for Δ: mean = 0.24 (SD = 16.39); for BA_E: mean = 80.9 (SD = 17.83), and for BA_EC: mean = 80.8 (SD = 11.1).
