Bland-Altman analyses between VLP- and NS1-MAC-ELISAs on JEV- and WNV-infected human sera. (A and B) Bland-Altman plots showing the differences in the average log-transformed P/N values of VLP- and NS1-MAC-ELISAs on JEV-infected (A) and WNV-infected (B) human serum specimens. The solid horizontal lines indicate the mean bias of the systematic difference between the two methods. The dashed horizontal lines indicate the 95% limits of agreement as the mean bias ±1.96 its standard deviation (SD). The dotted lines indicate the line of equality or zero difference between the two methods. The dashed and dotted horizontal lines indicate the 95% CI of the mean bias.
