- 79 persons were recruited to the study. Exclusion criteria in the recruitment were: diagnosed gastrointestinal disorders, antibiotic treatment in past two months, pregnancy, problems in blood coagulation, vegetarian diet and age below 18 or over 61. In addition, non-secretor persons (15) were excluded, thus the final study pool was 64 persons. Average age is presented together with the age range of each ABO blood group. Rh +/− states the presence/absence of the Rhesus-factor in blood.
- *No statistical difference (P > 0.95) was detected in participant numbers between blood groups.
- ** No statistical difference (P > 0.45) was detected in participant age distribution between blood groups.
