Kaplan–Meier curves showing overall survival (OS) for HIV patients and non-HIV patients having lung cancer. OS of all patients was shown according to expression status in IHC of CD4 (a, b), CD8 (c, d), CD56 (e, f), PD-1 (g, h), and PD-L1 (i, j). OS of the propensity-score-matched HIV patients and non-HIV patients having lung cancer was shown according to expression status in IHC of CD4 (k, l), CD8 (m, n), CD56 (o, p), PD-1 (q, r), and PD-L1 (s, t). OS overall survival, mOS median overall survival, mo month, NR not reached, PSM propensity-score matched, IHC Immunohistochemistry
