Heatmap and dendrogram describing clusters of co-occurring symptoms. Jaccard index was used to describe co-occurrence. Jaccard index is the ratio of the number of times two symptoms occur together divided by the number of times either of them appears. Jaccard index ranges from 0 (symptoms never appear together) to 1 (symptoms always appear together). Red square includes those symptoms clustered in patients presenting with MIS-C features. Blue square includes those symptoms co-occurring in patients presenting with respiratory disease. ARDS Acute respiratory distress syndrome
