Figure 1 Genotypic odds ratios for DCM and 95% confidence intervals, assuming a recessive (left) or dominant (right) genetic model. For all polymorphisms, the major allele was taken as the reference allele, except for ACE I/D where I was the reference allele. For TGFB1 R25P and BNP C-1563T, the recessive model was not considered because of the low frequency of the minor allele.
