CITM = Croatian Institute of Transfusion Medicine;

CITM-C = samples stored for 48 hours in a controlled refrigerator in CITM;

BRU 1 = airline transport Zagreb-Vienna-Brussels-Vienna-Zagreb with cooling elements;

BRU 2 = airline transport Zagreb-Vienna-Brussels-Vienna-Zagreb without cooling elements;

LON 1 = airline transport Zagreb-Vienna-London-Vienna-Zagreb with cooling elements;

LON 2 = airline transport Zagreb-Vienna-London-Vienna-Zagreb without cooling elements;

p*statistical significance of differences to non-transported samples stored in CITM;

p**statistical significance of differences between transported samples in controlled and uncontrolled conditions
