The hazard ratio was calculated by means of the Cox regression in patients diagnosed with serous carcinoma (n = 85), considering the clinical stage (I to III) and the differentiation grade (G1 to G3) as covariates, resulting in two groups of CA125 values: ≤500 and > 500 U/mL (referent). The gene discussed is MUC16; the disease is serous adenocarcinoma.
