^*CI = confidence interval n = number.

^†The first 15 predictors are baseline variables, and variables 16 to 21 represent the regression coefficients of the landmarks.

^‡Secondary vocational education, Level 2 higher than 1, included as dummy variables; MSI, self-reported musculoskeletal injury; hazard ratios for continuous variables refer to one unit change; landmark variables for the time-updated predictors can be interpreted as Health:1, Health:2, Health:3 and so on.
