Obese patients also presented significantly higher erythrocyte count, Ht and HOMAIR values and Hb, insulin and CRP levels (p<0.001 for all), but no significant differences in TB levels (p = 0.222), MCV (p = 0.432), MCH (p = 0.474), MCHC (p = 0.603), glucose (p = 0.389) or in UGT1A1 genotype distribution (p = 0.244).
