Table 4 The worst-case scenarios of physical, mental and autonomy decline in frail, pre-frail and robust persons according to the Puts, Fried and Steverink–Slaets models in the Crystal population

From: Do commonly used frailty models predict mortality, loss of autonomy and mental decline in older adults in northwestern Russia? A prospective cohort study

  Mental decline OR (95 % CI) Autonomy decline OR (95 % CI) Physical decline OR (95 % CI)
