Intent-to-treat means for fatigue and physical function ratings, the two measures that contributed to the criterion for improvement specified in the published protocol (Definition A in Table 1).

The relevant normative data for the Chalder Fatigue Questionnaire were obtained from [48], and those for the SF-36 physical function scale were obtained from [49].
