All data were expressed as the mean±SD. Normal distribution of data was tested with 1-sample Kolmogorov-Smirnov test. Difference by gender was analyzed using chi-square test. All statistical comparisons were performed using analysis of variance to compare multiple-group means. AOPPs - advanced oxidation protein products; AU - arbitrary units corresponding to percentage of H₂O₂ in standard solution; HT - hypertension; IMA - ischemia modified albumin; PAB - prooxidant-antioxidant balance; PCO - protein carbonyl; T-SH - total thiol; WCH - white coat hypertension; 8-OHdG-8-hydroxy-2’-deoxyguanosine.
