VDR and coronary artery disorder: The genotype frequencies comparison for the STEMI CAD group vs. control showed no statistically significant differences for the Fok1 (rs2228570) polymorphism, whereas for the BsmI (rs1544410) VDR the C/T genotype frequency was significantly lower and the T/T genotype frequency was significantly higher in the STEMI CAD group (χ2 test, p = 0.017) (Additional file 1: Table S4).
