Fig. 2From: An ELISA assay using a combination of recombinant proteins from multiple strains of Orientia tsutsugamushi offers an accurate diagnosis for scrub typhusCorrelation of IgG (Panel a) and IgM (panel B) ELISA OD with IFA titers. The ELISA OD of each sample was plotted against its corresponding titer. Panel a shows the correlation of IgG ELISA OD and IFA titers. The correlation co-efficient for IgG was 0.478 for Pearson and was 0.729 for Spearman (p < 0.0001). Panel b shows the correlation of IgM ELISA OD and IFA titers. The correlation co-efficient for IgM was 0.650 for Pearson and was 0.765 for Spearman (p < 0.0001). The mean and standard deviation of ELISA OD of all samples within a given IFA titer is was plotted in redBack to article page
