Heightened plasma levels of matrix metalloproteinases (MMPs) in multisystem inflammatory syndrome in children (MIS-C) and acute COVID-19 children. The plasma levels of MMP-1, 2, 3, 7, 8, 9, 12 and 13 were measured in MIS-C (n = 65), acute COVID-19 (n = 56), children with other diseases (n = 40), convalescent COVID-19 (n = 47) and control children (n = 21). The data are represented as scatter plots with each circle representing a single individual. p values were calculated using the Kruskal-Wallis test with Dunn’s post hoc for multiple comparisons.
