Figure 1.

The ocular components displayed biphasic age-related patterns. (A) The power (R²) and P value for age-related patterns of multiple variables simulated with the linear regression model (first order) or second-, third-, or fourth-order polynomial regression models. (B, C) The best fitted age-related growth patterns of (B) AL and (C) ACD showed an inverted U shape. (D) The best fitted age-related pattern of LT showed a U shape. The dashed lines indicate the X and Y positions of the inflection point. The second-order polynomial regression formula for each variable as a function of age, and the P values were provided. Red for females and blue for males.
