Comparison between the expected and observed prevalence of combined carriers of mutations in MI patients and control subjects.

(A) Comparison between the expected and observed prevalence of combined carrier for the FII 20210A + FXIII-A Leu34 alleles in MI patients and control subjects, respectively. (B) Comparison between the expected and observed prevalence of combined carrier for FVL + FXIII-A Leu34 alleles in MI patients and control subjects, respectively. Filled bar (▪) represents the observed prevalence of combined carriers. Empty bar (■) represents the expected prevalence of combined carriers.
