Abbreviations: KD, Kawasaki Disease; MIS-C, Multisystem Inflammatory Syndrome in Children; LAD, left anterior descending coronary artery; RCA, right coronary artery. Values are presented as mean ± SD or frequency (percentage). P-values were calculated using Student’s t or Mann-Whitney U tests for continuous variables and Chi-square or Fisher’s exact tests for categorical variables
