Temporal changes in physical symptom scores after exercise in chronic fatigue syndrome patients and healthy controls estimated by linear mixed models with the baseline period of one week before exercise numbered as “day 0”. There were significant main effects of the group and time of the day and a significant group × time of the day interaction, and a group × day interaction only after the fifth day. Closed squares indicate scores of chronic fatigue syndrome patients and closed circles indicate scores of healthy controls. Error bars shows standard error of means of physical symptom scores. CFS, patients with chronic fatigue syndrome; CON, healthy controls.
