Specifically, age (P = 0.006), Ki-67 expression level (P = 0.013), Ann Arbor staging (P = 0.027), International Prognostic Index (IPI) score (P < 0.001), ECOG score (P = 0.007), rituximab application (P = 0.044), LDH expression level (P = 0.038), and the presence of combined MetS (P = 0.015) were found to be statistically associated with OS (Table 3). Here, MKI67 is linked to metabolic syndrome.
