  1. χ2-test was used to determine statistically significant relationships among categorical variables
  2. a Normal values, depending on the date of the blood draw and the age/sex of the patient, are accurately described within the section “Subjects and Methods”;
  3. b Normal values, depending on the age of the patient, are accurately described within the section “Subjects and Methods”
