Notes. ^a278 baseline respondents who are lost to follow-up in all subsequent waves but not dead are omitted.

^bNot applicable since everyone in this age bracket and trajectory group has a limitation at baseline.

^cNot applicable since everyone in this age bracket and trajectory group are without limitation at baseline.
