Kaplan Meier survival curve for NSCLC patients stratified by NLR systemic inflammation, NLR < 5 and NLR ≥ 5 (n = 184), showing worse survival probability (p = 0.001) for patients having greater inflammation (i.e., above NLR cutoff).
The hazard ratio for elevated PLR is 2.08 (95% CI: 1.34, 3.22; p = 0.001), comparable to the association between NLR and survival. Patients with baseline PLR<185 (43%) had a one-year survival probability of 0.78 (95% CI: 0.69, 0.89), while those with a baseline PLR≥185 (57%) had a one-year survival probability of 0.49 (95% CI: 0.41, 0.59). The log-rank test was significant (p = 0.005), indicating a significant difference in survival between groups (
