The univariate analysis presented the following clinicopathological indicators associated with OS: intestinal obstruction, TNM stage, CA125 level, CD8+ T lymphocyte count, NLR, LMR, and mSIS (Alb level <40 g/L and LMR < 3.0) (P < 0.05, Table 2). This evidence concerns the gene CD8A and intestinal obstruction.
