a N = 4627 (17,291 observations; 330 cancer survivors and 4297 individuals with no cancer history). b Coefficients are based on random slope coefficient models adjusted for the covariates; * p < 0.05. ** p < 0.01. *** p < 0.001; c Intercepts indicate person-specific baseline level of weekly hours worked. d Linear slopes describe intra-individual patterns of change in weekly hours worked as a function of centered time (ctime).
