Correlation between plasma C reactive protein (CRP) and angiopoietin-like protein 4 (ANGPTL4). Correlation between plasma C reactive protein (CRP) and angiopoietin-like protein 4 (ANGPTL4). Plasma was taken from healthy controls, patients with metabolic syndrome without and with low-grade inflammation and patients with type 2 diabetes mellitus, and plasma ANGPTL4 levels as well as CRP levels were determined. Plasma CRP correlates positively with plasma ANGPTL4 (r=0.295, p<0.001). Nathanja Tjeerdema et al. BMJ Open Diab Res Care 2014;2:e000034 ©2014 by American Diabetes Association
