SS patients, patients with SS sickle cell disease; SC patients, patients with SC sickle cell disease; Hb, hemoglobin; HbS, hemoglobin S level; MCV, mean corpuscular volume; AST, level of aspartate aminotransferase; LDH, level of lactate dehydrogenase. The bold values indicate the statistically significant results.
