When we stratified eligible studies by type of disease, positive results were observed for rs17568 variant in subjects with acute coronary syndrome (ACS) (allele model: P = 0.04, OR = 0.81, 95%CI, 0.65-0.99), for rs1234314 variant in subjects with coronary artery disease (CAD) (dominant model: P = 0.04, OR = 1.16, 95%CI, 1.00-1.35), for rs3850641 variant in subjects with CAD (recessive model: P = 0.02, OR = 1.42, 95%CI, 1.05-1.90) and myocardial infarction (MI) (recessive model: P = 0.03, OR = 1.49, 95%CI, 1.05-2.11).
The results showed that carriers of the G allele of rs17568A/G had a significantly increased risk of ACS (p = 0.023, adjusted odds ratio = 1.72, 95% confidence interval = 1.08-2.75) after adjusting for age, sex, diabetes, hypertension, and lipids.
