  1. * vs. HC of Cohort 1; ** vs. HC of Cohort 2; and *** vs. CFS+MA using 2-tailed unpaired Student's t-tests with Bonferroni corrections after ANOVA. Neuro-Construct = sum of scores for poor memory, dizziness, balance problems, and numbness in arms or legs. Cardio-Construct = sum of scores for rapid heart rate, irregular heart rate, palpitations, and chest pain.
