a Kaplan–Meier curves for overall survival (OS) in a cohort of patients (n = 83) diagnosed with PDAC, according to relative expression levels of miR-93. OS showed divergent Kaplan–Meier curves according to miR-93 status. P values determined by log rank Mantel Cox test. b Relative miR-93 expression in patients with OS > 6 months compared to patients with OS < 6 months. Student’s t test. c Kaplan–Meier curves for resectable PDAC (n = 33) or d non-resectable PDAC (n = 48).
