From: CA19–9 decrease and survival according to platelet level in patients with advanced pancreatic cancer
Kaplan-Meier curves of PFS according to CA19–9 decrease in strata of baseline platelet level (a. All patients, b. Patients with low platelet level, c. Patients with intermediate platelet level, d. Patients with high platelet level). The HR were calculated using univariate Cox regression model compared patients who experienced a CA19-9 decrease at week-6 above 20% with patients who did not
