Venn diagram to demonstrate concordance between serological assays and CT NAAT results. The diagram shows the number of participants positive in each of the assays and those who were positive in more than one assay. The two MOMP assays (MEDAC IgG and ANIlab) and NAAT results showed considerable concordance. The samples that were negative in all assays are also indicated on the figure, only the 162 samples that had a valid result in all of these assays are included in the Venn diagram
