Principal component analysis performed on miRNAs expression levels in pooled plasma samples from healthy subjects and pancreatic cancer patients. Healthy subjects were stratified according to the category of risk for pancreatic cancer development (blue circles: Pool₁, Pool₂, Pool₃), and to the date of diagnosis of diabetes (red circle: Pool₄, Pool₅); patients with pancreatic cancer were classified based on the preoperative stage of the disease (purple circles: Pool₆, Pool₇, Pool₈), and on the date for patients diagnosis of diabetes (green circles: Pool₉, Pool₁₀).
