ABO and Rh D, C, c, E, e were obtained by serological typing, while other blood groups were obtained by PCR-SSR. HWE analysis is considered significantly different if their P value is < 0.050
n sample size, na not applicable, P significance level (P value), HWE Hardy–Weinberg equilibrium
^ǂP value for HWE analysis in Duffy blood group was then adjusted to < 0.013 using Bonferroni correction
