Follow-up data on the ALT and indices of iron status in 12 patients with transfusional iron overload on iron chelation with DFO.

Individual patients may be identified within the different panels by use of a single symbol and color for each patient. Urinary iron excretion was not measured in patients 3 and 12. The horizontal line in panel A represent the upper reference limit for ALT serum activity (40 U/L).
