APOA5 and coronary artery disorder: The association between the APOA5 -1131 T>C polymorphism and lower blood HDL-C under dominant model was significant in CHD subjects: for the analysis including all studies on subjects with CHD: SMD = -0.12, 95% CI (-0.23, -0.01), P = 0.04, Pheterogeneity = 0.61, and for the analysis excluding the studies not in HWE: SMD = -0.12, 95% CI (-0.24, -0.01), P = 0.04, Pheterogeneity = 0.42 (Table 2).
