English: 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. Estimates of healthy performance for the fatigue and physical function measures are based on previously published samples that further excluded the elderly (over 60), and those with a significant medical condition (95% CI bands = upper and lower bounds of 95% confidence interval). The relevant normative data for the Chalder Fatigue Questionnaire were obtained from "Fatigue in the general Norwegian population: normative data and associations." by Loge JH, Ekeberg Ø, and Kaasa S, and those for the SF-36 physical function scale were obtained from "Short form 36 (SF-36) health survey questionnaire: which normative data should be used? Comparisons between the norms provided by the omnibus survey in Britain, the health survey for England and the Oxford healthy life survey" by Bowling A, Bond M, Jenkinson C, and Lamping DL. In the case of the SF-36 scale, the healthy sample was highly negatively skewed, so medians are reported. The median score for this sample was 100 (95% confidence intervals: 100,100).
