Number of genotypes recognised by serum antibodies. In secretor individuals (n = 43) the data show that these serum samples contain antibodies against 3.3 genotypes as a mean. Besides, non-secretor population serum samples (n = 12) were able to recognize 3.6 genotypes. These data were analysed statistically (non-parametric test from unpaired samples) to confirm that there are non-differences between secretor and non-secretor (P > 0.05). Error bars represent the standard mean error (SEM).
