Total antioxidant capacity expressed as FRAP [mmol/L] in the blood of subjects undergoing routine HRCT examination before the test, 10 min, 20 min, 60 min and 120 min after the test. The analysis was carried out using the Wilcoxon test for dependent (repeated) measurements; the graph shows the medians, quartiles and ranges of values of individual variables. * p—comparison with the measurement before the examination (* p < 0.05, ** p < 0.01, *** p < 0.001)—Wilcoxon test for dependent (repeated) measurements.
