R1 to R4, (H6-ED3-PhoA)2 dimers of serotypes DENV1 to DENV4, respectively. The first column gives the serotype of the infecting DENV for the (+) serums. DENV1-4, the serotype of the infecting virus could be any one of DENV1 to DENV4. The DENV-uninfected serums were always taken as (−) serums. Each entry gives the accuracy and associated standard error of a MAC-ELISA that used the Ri reagent (i = 1, …, 4) as an antigen and was evaluated on the (+) and (−) serums.
