Prevalence of Independence at Visit 2 in Survivors.

Visit 2 Prevalence in Survivors	Valid Data and Survived to Visit 2	Difference in Prevalence of Independence from Baseline to Visit 2 in Survivors (95% CI)
Status at follow-up:
Overall independent (valid)	159 (61.6%) (n = 258)‡	−26.0% (−33.1; −18.8)
Overall independent (all)	183 (59.6%) (n = 307)	−26.7% (−33.4; −20.0)
Physically independent	253 (74.9%) (n = 338)	−21.3% (−26.4; −16.2)
Cognitively independent (valid)	204 (81.6%) (n = 250)	−12.4% (−18.0; −6.8)
Cognitively independent (all)	249 (75.0%) (n = 332)	−16.0% (−21.6; −10.4)

Note: MMSE = Mini-Mental State Examination.

*Valid refers to using only valid MMSE exams.

^†All refers to using all MMSE exams.

^‡These n’s do not match those in Table 1. due to some participants having valid data at visit 2 but not at visit 1.
