From: Frailty, fitness and late-life mortality in relation to chronological and biological age
Cumulative proportion of surviving as a function of time to death for two groups with chronological age (A) and biological age (B) less and greater than 80 years. Circles correspond to experimental data for individuals below 80 years old and triangles for individuals above 80 years. Curves correspond to the least square Gompertz's functions (solid lines fit data for the individuals below 80 years and dashed lines for those who was older than 80 years).
