Figures and Figure Legends
Figure 1. Graphical representation of clinical course of four patients included in the case series. Timeline includes up to day 40 of illness, or until death or discharge, whatever occurred first. PCR – polymerase chain reaction; HCQ – hydroxychloroquine; ECMO – extracorporeal membrane oxygenation.
Figure 2. Longitudinal serum SARS-CoV-2 antibody titers in pediatric patients receiving convalescent plasma transfusion therapy.  Antibody titers expressed as reciprocal serum dilution against SARS-CoV-2 antigens in four pediatric patients (CD4, CD15, CD17 and CD25) and corresponding convalescent plasma donors (CP; open symbols) before and after plasma transfusion. Antibody titers against (a-d) the SARS-CoV-2 receptor binding domain of the spike (S) protein, (e-h) the full-length SARS-CoV-2 S protein (FL), and (i-l) the nucleoprotein of SARS-CoV-2 (N). Dashed lines denote the lower limit of detection (LLOD) of the assay (1:50 serum dilution)
