Kaplan-Meier survival curves illustrating progression-free survival (PFS). A Patients receiving chemotherapy plus immune checkpoint inhibitors (ICI), stratified by baseline C-reactive protein (CRP) levels (elevated vs. normal). B Patients receiving chemotherapy alone, stratified by baseline CRP levels (elevated vs. normal). The ‘+’ symbols represent censored data points, indicating times at which patients were lost to follow-up without experiencing the event of interest. The log-rank test was used to compare the survival distributions, and the difference was found to be statistically significant (p < 0.05)
