* A. seroprevalence - apparent seroprevalence, CI- confidence interval, OR- odds ratio
NB. While analyzing, the model excludes those that did not have at least one seropositive sample. As a result, the chi-square and p values are calculated from the samples that have at least one antibody positive sample
