Hematocrit and right ventricular hypertrophy: (a) hematocrit (%) and (b) right ventricular hypertrophy (RVH), calculated by the right ventricle/left ventricle + septum (RV/LV + S) ratio, for all of rats exposed to CIH2x2, CH, and NX. Values are expressed as means ± SEs. Statistical comparisons were performed using repeated measures ANOVA for (a) and one-way ANOVA for (b);   is exposed versus NX and   CH versus CIH2x2.
