ANGPTL8 and metabolic syndrome: There was no difference in circulating ANGPTL3 concentrations between the dyslipidemia and no-dyslipidemia groups (P = 0.097) (Additional file 2: Figure S1), consistent with the study by Guo et al. [51], nor was there any association between circulating ANGPTL3 and ANGPTL8 concentrations (P = 0.160 and P = 0.100, respectively) (Additional file 1: Table S1).
