Proportions of three MIS-C classes over time. Each line represents the proportion of the three classes over 3-month periods. The proportions of the classes are calculated using the average of the posterior class membership probabilities of the patients who are diagnosed in the given time window. The calendar time is segmented quarterly. Time intervals with small sample sizes are combined and labeled by a star. (a) Proportions of the three latent classes across time. Each line represents a class. (b) Histogram of the number of patients in each time window, including timing of predominant SARS-CoV-2 variant activity.
