Fig. 2

Mean erythrocyte filterability in groups A (control subjects, n = 14), B (non-obese, diabetic patients, n = 29), and C (obese, non-diabetic patients, n = 32). Baseline filterability showed a significant (p < 0.001) difference among the groups of A, B (pre), and C (pre). Erythrocyte filterability was significantly improved in group B (p < 0.001) and group C (p < 0.001) after the fulfillment of the BOOCS program. Columns and bars indicate means and standard errors, respectively. RCF red cell filterability (%). *p < 0.001 indicates a significant difference in baseline RCF among the three groups, and ^# p < 0.001 denotes a significant improvement of RCF within a group
