Figure 2. Association of serum LDH levels and OS of patients with advanced pancreatic cancer in the validation cohort (n = 225).

Figure 2

Kaplan–Meier analysis of OS of patients in the validation cohort. The median LDH concentration of samples was 185 IU/mL and was selected as the cut-off between high and low LDH levels. The p-values were determined using the log-rank test. Kaplan–Meir curves were generated as functions of the variables as follows: (a) LDH levels, (b) disease stage, (c) CA19-9 concentrations, (d) NLR and (e) LMR.
