aAll numerical variables were dichotomized based on the median levels in patients except for MMP-9 which was dichotomized based on the mean value.
bUnivariate analysis included all variables that showed significant differences among children with RHD without HF and children with RHD and HF.
cMultivariate analysis included all variable that were significant indicators in the univariate analysis. Significant P-values are shown in bold print. RHD, rheumatic heart diseases; HF, heart failure; Hb, hemoglobin; TLC, total leukocyte count; ASO, antistreptolysin O; MMP-9, matrix metalloproteinase 9.
