Intercept R2\Q2
C vs. Hom vs. Het 39 0.351 0.484 0.159 ns 0.27/−0.14
Het vs. Hom 13 0.515 0.699 0.246 ns 0.73/−0.03

C= control patients; Het = heterozygous for β-thalassemia patients; Hom = homozygous for β-thalassemia patients; N, number of samples; R2X, R2Y, values indicating the variance of the model; Q2, value indicating the predictive ability of the model. The p-value was considered significant for values <0.05.
