Table 2.
Contribution of each pattern to the G2 and Pearson chi-squared test statistics. “+” = positive, “−” = negative, “?” = indeterminate. LFA = lateral flow assay; ELISA = enzyme-linked immunosorbent assay; MBA = multiplex bead array. Model with two latent classes utilizes Model 19 from Table 1 and Model with three latent classes utilizes Model 22 from Table 1.
