Table 1 Point estimates (PE) of marginal loss in life expectancy (LLE), life expectancy (LE_C) and expected life expectancy (LE_exp) for cancer patients together with PE of marginal loss in 15-year restricted mean survival times (LRMST), observed 15-year restricted mean survival time (RMST_C) and expected 15-year restricted mean survival time (RMST_exp) for cancer patients, with standard errors (SE), relative % precision (RP), lower (LCI) and upper (UCI) 95% confidence intervals. RP illustrates the comparison of the modelling approaches. All the estimates are measured in years
