However, multivariate Cox regression model analysis showed that ITGA3 expression level was only correlated with PAAD overall survival in TCGA (HR = 1.396, 95% CI 1.135–1.716, p = 1.58 × 10−3) and in the GSE62452 dataset (HR = 1.450, 95% CI 1.049–2.005, p = 2.47 × 10−2) after adjusting the confusing factors (age or TNM classifications; Table 3). Here, ITGA3 is linked to pancreatic adenocarcinoma.
