aChi-square test performed on categorical variables and analysis of variance (ANOVA) test on continuous variables. If the P-values of the comparison are smaller than 0.05, it is considered that there are significant differences between the two groups. Any significant findings will be represented with P-values in bold font
LMA large mediastinal adenopathy, RER rapid early responders, se standard error, SER slow early responders
