Models were adjusted for age at retirement. Period 1 = years −4 to −2 (preretirement); period 2 = years 1− to +1 (periretirement); period 3 = years +2 to +4 (postretirement).

^*p Values (two sided) refer to interaction time × period × covariate (except for all, where p value refers to period main effect).
