*OR (odds ratio) = ratio of risk for poor performance (n = 73 elderly women with good performance and n = 25 elderly women with worse performance); CI 95%, OR = 95% interval of confidence for the risk ratio; ref: reference level; n = 98.
**OR (odds ratio) = ratio of risk for poor performance (n = 24 elderly women with TUG 1 (≤10 s), n = 59 elderly women with TUG 2 (10.01 - 20 s) and n = 13 with TUG 3 (over 20.01 s)); CI 95% OR = 95% interval of confidence for the risk ratio; ref: reference level Proportional hazards model. n = 96.
