Subsequently, these characteristics were incorporated into a multivariate Cox regression analysis; the result showed that high PDSS1 expression (HR = 2.505; 95% CI: 1.530 – 4.100; p < 0.001) and tumor status (HR = 1.741; 95% CI: 1.081 – 2.802; p = 0.023) were independent prognostic factors for poor prognosis (Figure 2D). This evidence concerns the gene PDSS1 and neoplasm.
