For diseases that run a clinical course over long periods, survival analysis is conducted with n-year survival or with clinical life tables. The n-year survival refers to the proportion of patients surviving for n years after diagnosis. Clinical life tables are used in order to deal with the disadvantages of n-year survival use. Clinical life tables are constructed by the actuarial method or Kaplan-Meier method.
