PCSK9 and type 2 diabetes mellitus: In patients with T2DM, as compared with patients without T2DM, we observed a trend toward higher levels of plasma PCSK9 (p = 0.092) and lower number of CD45neg/CD34bright (p = 0.072), CD45neg/CD34bright/CD146neg (p = 0.051) and CD45neg/CD34bright/CD309pos (p = 0.072) although these trends did not achieve statistical significance.
