When analyzing differences in the TrxR1 level between the control group and the three severity grades of the aortic valve stenosis, we obtain statistically significantly (p = 0.0001) higher TrxR1 levels in patients with mild aortic valve stenosis and severe aortic valve stenosis (p = 0.047), see Figure 5. This evidence concerns the gene TXNRD1 and aortic valve stenosis.
