	Predicting loss of function in 1 year

Functional tests	Area Under ROC Curve	Cut-off Time or Distance	Sensitivity	Specificity
10 meter walk/run	0.93(0.88–0.97)	>7.6s(7.6s–09.2s)	93% (79%–100%)	82% (77%–95%)
4 Stairs	0.96 (0.92–0.99)	>6.2s (4.5s–7.4s)	90% (80%–100%)	91% (79%–97%)
STS	0.96 (0.93–0.99)	>6.6s (6.3s–7.9s)	97% (91%–100%)	91% (85%–96%)
6MWT	0.85 (0.76–0.93)	<319m (277m–335m)	77% (66%–90%)	85% (70%–100%)
