Moreover, the clinical trial with patients treated with a KD due to drug-resistant epilepsy showed that 12-month adherence to KD resulted in an increase in HBG, HCT and MCV, while no effect on other haematological parameters (red blood cell, white blood cell and platelet counts, serum iron, total iron-binding capacity, transferrin saturation, and ferritin and folic acid levels) was observed [54]. This evidence concerns the gene TF and epilepsy.
