FI = frailty index; OR = odds ratio; CI= confidence interval.

^aIncident falls: n = 483 (21.33%) for year 2 post-baseline; n = 288 (17.04%) for year 3 post-baseline. Incident death: n = 43 (1.09%) for year 2 post-baseline; n = 25 (0.64%) for year 3 post-baseline.

^bFor year 2, changed values were from year 1 minus baseline, denoted as FI_{(year 1– baseline)}; for year 3, changed values were from year 2 minus year 1, denoted as FI_{(year 2 – year 1)}.

^cFor year 2, information was from year 1; for year 3, information was from year 2.
