Figure 1: Receiver operating characteristic curve for the six-minute walk test:
Receiver operating characteristic curve for the six-minute walk test with increased fall risk or no fall risk as the outcome. Black diagonal line is a reference for 0.50 area under the curve. Area under the curve = 0.701 (0.570–0.832) p=0.006. Cutoff point is 331.65 meters, SN=0.74, SP=0.63.
