Although our study primarily focused on classical inflammatory and myocardial stress biomarkers (e.g., CRP, IL-6, NT-proBNP, and troponin), it is worth noting that recent evidence supports the neutrophil-to-lymphocyte ratio (NLR) as a simple, yet powerful, predictor of adverse outcomes in COVID-19, including MIS-C. This evidence concerns the gene IL6 and COVID-19.
