1. Diethylamine-based measles avidity assay.
Diethylamine-based measles avidity assay. Shown are box-and-whisker analyses of results over three time intervals from samples with good epidemiological records, collected from persons aged ≥9 months (A), and samples shown in panel A and samples with uncertain epidemiological information, collected from persons aged ≥3 months (B); some assumptions were made for 99 samples. The asterisks indicate outliers within sample group A. The open symbols are values smaller (larger) than the lower (higher) quartile minus (plus) 1.5 times the interquartile range. The solid symbols are values smaller (larger) than the lower (higher) quartile minus (plus) 3 times the interquartile range. The low-avidity threshold is 30%. The high-avidity threshold is 70%.
