Box and whisker plot of CloFAL AUC for participants of the COVAC-TP trial with COVID-19 and MIS-C. The P values presented below plots for each day represent comparisons of values between those with COVID-19 and MIS-C. The P values with brackets above the plots represent comparison of pooled values for each day as compared with day 0. Total samples analyzed by study time point are as follows: day 0 (n = 20), day 1 (n = 24), day 2 (n = 19), day 3 (n = 17), day 7 (n = 8), and day 14 (n = 4).
