Univariate and multivariable analyses were conducted on nutrition-related indicators, including body mass index (BMI), albumin (ALB), hemoglobin (Hb), diabetes mellitus (DM), and hyperlipidemia, along with clinicopathological characteristics that might affect patients’ first-line chemotherapy response, progression-free survival (PFS), and overall survival (OS). Here, GSTM1 is linked to hyperlipidemia.
