Age-adjusted NT-proBNP could help in the early identification and follow-up of children at risk for severe multisystem inflammatory syndrome associated with COVID-19 (MIS-C)

Table 7 Correlation analysis of the relationship between N-terminal pro-brain natriuretic peptide and all the cardiac continuous variables explored in this study

NT-proBNP (Z-log value adjusted for age)	Correlation coefficient	P value
hs-TnI (ng/L)	0.47	0.045
Age-based Ross score for heart failure	0.76	0.003
LVEF (%)	-0.55	0.021
Maximal CA diameter	-0.21	NS.

NT-proBNP: N-Terminal Pro-Brain Natriuretic Peptide; Hs-TnI: High sensitivity-troponin I; LVEF: Left ventricle ejection fraction; CA: Coronary artery; NS. (P > 0.05).
