Preexercise multivariate GLM with CFS status, Orthostatic status and gender as fixed factors, and age and BMI as independent variables was significant (Wilks’ lambda = 0.202, p = 0.036, Partial Eta Squared = 0.798). Orthostatic status, BMI and gender were not significant covariates. Estimated marginal mean ± 95%CI. BOLD signal amplitudes were higher in control than CFS by univariate significance.
