The training data set to determine predictors used the active-TENS group with an intention-to-treat analysis with response to TENS data from Visit 3 (n=103). The validation data set used the placebo-TENS and No-TENS groups who completed Visit 4 (n=155). These two groups received active-TENS for 1-month starting at Visit 3 and continuing to Visit 4.
