*OR (odds ratio) = ratio of risk for poor performance (n = 73 with good performance and n = 25 with worse performance); CI 95% OR = 95% interval of confidence for the risk ratio. Stepwise criterion for variable selection; n = 98.
**OR (odds ratio) = ratio of risk for poor performance (n = 24 with TUG 1 (≤10 s), n = 59 with TUG 2 (10.01 – 20 s) and n = 13 with TUG 3 (over 20.01 s)). Proportional hazards model. CI 95% OR = 95% interval of confidence for the risk ratio. Stepwise criterion for variable selection; n = 96.
