Predictors of Gait Speeds and the Relationship of Gait Speeds to Falls in Men and Women with Parkinson Disease

Figure 1

ROC curves for SELF (black), FAST (red), and DIFF (green) predicting fallers in the total sample. DIFF was also used to predict fallers, respectively, in men (blue) and women (cyan). SELF and FAST were strong predictors of fallers in the pooled sample. DIFF was a strong predictor of fallers in men but not women (see Table 5 for AUC, sensitivity, and specificity values).
