IgG responses in OD ratio ± standard error.
N = number of positive responders that is individuals with OD ratio ≥2, (%) = prevalence of positive responses, ODrt = Mean Optical Densities ratio, SE = standard error, = value resulting from comparison with Mann-Whitney rank or Chi2 tests employed, respectively, for ODrt and prevalences of responders.
