Hazard ratios of self-rated health (SRH), sex/gender, and education for mortality during four-year follow-up in Cox modelsa.

aInteraction terms were excluded in the models when we reported the HRs and 95% CIs on the table (effect-only models).bHR of each cell in Model 1B was calculated by each different model. In contrast, HR of sex/gender and that of education (and that of depression after Model 3B) were calculated simultaneously by a single model in Model 2B, 3B, 4B, and 5B.cAs depression was included as the control variable in Model 3B in addition to the variables in Model 2B, HR of depression in Model 2B was not reported.
