Efficacy prediction of PD-1 immunotherapy based on lactate metabolism in patients with lung adenocarcinoma. A Kaplan–Meier analysis demonstrated that the PFS of patients in the high-risk group were significantly shorter than those of the low-risk group. B The ORR of patients in high-risk and low-risk groups. C Box plot of the risk scores for different anti-tumor treatment responses. D The OS of patients in the high-risk and low-risk groups. E, F Time-dependent ROC curves for recurrence and mortality of patients at different follow-up times. *P < 0.05
