Multivariate Cox Regression Analysis for PFS

Variable Name	Hazard Ratio	Confidence Interval	p Value
Age	0.94	0.90–0.98	0.006
Sex (female vs. male)	1.20	0.62–2.33	0.588
Albumin	0.94	0.89–1.00	0.055
NLR	1.08	1.02–1.14	0.005
LDH	1.09	0.97–1.22	0.148
Cycles of EP	0.57	0.37–0.89	0.011

EP, etoposide platinum (carboplatin) chemotherapy; LDH, lactate dehydrogenase; NLR, neutrophil-to-lymphocyte ratio; PFS, progression-free survival.
