  1. Lists the demographic and hematological parameters studied. Data are presented as n (%) for categorical variables, median (Interquartile Range, IQR) for non-normally distributed continuous variables, and mean ± standard deviation (sd) for normally distributed continuous variables. The standards of error analysis and ranges have been accounted for in the provided IQR and sd.
