Moreover, the OS was longer in the PN group (21.71 ± 5.82 months) than in the PP group (20.01 ± 5.18 months), although the difference was marginally significant (t = 2213.5, P = 0.041).

However, the distribution of pathological type (adenocarcinoma and squamous carcinoma) displayed borderline significance (c 2 = 3.230, P = 0.072), which suggests a potential trend warranting further investigation.
Similarly, a negative correlation was observed between PD-1 expression and OS, though it did not reach statistical significance (r = −0.154, R 2 = 0.024, P = 0.091).
