Univariate analysis of the relationship of age, sex, smoking history, tumor location, clinical stage, NLR, PLR, CNP score, and Hb level and prognosis revealed that elevated PLR (p = 0.019), elevated CNP score (p = 0.048), and a decreased Hb level (p = 0.003) were associated with decreased OS. Here, CNP is linked to neoplasm.
