Other variables, including CA-125 values (HR 0.77, 95% CI 0.47–1.27, p = 0.312), tumor grade (HR 1.09, 95% CI 0.62–1.93, p = 0.758), surgical complexity (HR 0.87, 95% CI 0.50–1.52, p = 0.631), neoadjuvant chemotherapy (HR 0.79, 95% CI 0.45–1.40, p = 0.423), and pleural effusion status (HR 0.64, 95% CI 0.36–1.16, p = 0.140) showed no significant association with either mortality or disease progression in the univariate analyses (Table 2). This evidence concerns the gene MUC16 and Pleural effusion.
