Three multivariate regression models of EImax for the non-GP.Mur normocytic, GP.Mur normocytic, and GP.Mur microcytic groups. The models for the non-GP.Mur normocytic and GP.Mur microcytic groups could be explained by the two independent variables, membrane cholesterol and MCV, with significance, but the model for the GP.Mur normocytic group could not. These three models revealed distinctly different contribution of membrane cholesterol contents and MCV to deformability with respect to GP.Mur type and microcytosis. *** p < 0.001; ** p < 0.01; * p < 0.05; n.s., not significant.
