  1. Reference values were established in three different groups and are expressed as median, minimum and maximum values. The Mann-Whitney U test showed statistical differences between groups 1 and 2 (U = 28.8; p < 0.001), between groups 1, 2 and 3 (U = 9.0; p < 0.001) and between groups 2 and 3 (U = 34.0; p < 0.001). Units = µmol aMT6s /mol creatinine.
