Prognostic value of baseline clinicopathological characteristics in first-line chemotherapy ± immunotherapy for extensive-stage small cell lung cancer: a retrospective cohort study.

It was worth noting that in the chemoimmunotherapy cohort, an LDL level of >1.8 mmol/L significantly improved patient prognosis in terms of PFS (P=0.003; HR =4.59; 95% CI: 1.52, 13.90) ( Figure S1 ), while in the chemotherapy cohort, an LDL level of ≤1.8 mmol/L showed a trend toward improved patient prognosis ( Figure S2A ).
