Matrices of natural logarithm-transformed
PRNT titers from primary
DENV exposures stratified by
strain. The “n” on the upper right of each exposure column represents the number of titers, filled squares indicate the pooled median log titer for all strains within that particular box, diamonds with crosshairs represent median log titers for strains, horizontal lines span the 25th-75th percentiles (interquartile range), and vertical lines mark the 5th and 95th percentiles of the data.
