Study cohort and inflammatory laboratory values. A, Basic demographic characteristics of the study cohort. B and C, Inflammatory laboratory values. Normal ranges are depicted in gray shading. Significance was tested using Wilcoxon test and adjusted for multiple comparisons by controlling false discovery rate using the Benjamini–Hochberg method. Adjusting results for age, sex, and body mass index of participants increased statistical significance for absolute lymphocyte count (ALC) at admission (P = .0337) and ALC nadir (P = .0127). See Supplementary Table 2 for details. Abbreviations: ALC, absolute lymphocyte count; ALT, alanine aminotransferase; AST, aspartate aminotransferase; CFR, children fully recovered from coronavirus disease 2019; COVID-19, coronavirus disease 2019; CRP, C-reactive protein; F, female; M, male; MIS-C, multisystem inflammatory syndrome in children; proBNP, prohormone B-type natriuretic peptide; SAC, severe acute coronavirus disease 2019 in children; WBC, white blood cell count.
