Furthermore, a multivariable Cox regression model, adjusted for clinically relevant factors (including age, tumor characteristics, nodal involvement, menstruation, radiotherapy, chemotherapy, vascular invasion, and TNM stage) revealed a significant association between tumor cell SDC1 expression and CD24 expression [HR:1.98 (95% CI 1.38–2.84), P = 0.0002], as presented in Table 5. Here, CD24 is linked to neoplasm.
