Survival functions (conditional on survival to age 80) for the LLFS participants in comparison with 1900 and 1920 birth cohorts: (a) U.S. females; (b) U.S. males; (c) Danish females; (d) Danish males. The LLFS curves are shown by solid thick line with 95% confidence intervals indicated by solid thin lines. Dashed lines display population survival functions from corresponding cohort life tables: Social Security Administration (SSA) for USA and Human Mortality Database (HMD) for Denmark. The numbers after SSA and HMD show the respective birth cohort.
