APOC3 and metabolic syndrome: Meta-analysis of the overall sample indicated that significantly more APOC3 -455C allele carriers met the MetS criteria for elevated blood pressure (32.9% vs 29.3%, P = 0.039), depressed HDL cholesterol (39.8% vs 30.9%, P = 0.0002), and elevated triglycerides (28.1% vs 18.6%, P < 0.0001) than non-carriers, and tended to meet the criteria for fasting glucose (22.0% vs 20.0%, P = NS[0.061]), but not for waist circumference (33.7% vs 33.4%, P = NS[0.45]).
