PRDX2 and colorectal carcinoma: Moreover, multivariate analysis showed that the independent prognostic variables for DSS included patient age (HR = 1.652, 95% CI=1.030–2.649, p = 0.037), PRDX2 expression (HR = 2.046, 95% CI = 1.270–3.296, p = 0.003), tumor differentiation grade (HR = 1.671, 95% CI = 1.079–2.589, p = 0.022), and TNM stage of CRC (HR = 1.578, 95% CI = 1.030–2.417, p = 0.036) (Table 2).
