* A DIPSS score of 0 (low risk) was assigned for haemoglobin level greater than 10 g/dl and a blood cell count between 4x109/l and 30x109/l, score of 1 (intermediate risk) for either a haemoglobin level less than 10g/dl or a white blood cell count greater than 30x109/l or less than 4x109/l, and a score of 2 (high risk) if both the haemoglobin level and white blood cell count were in the aberrant ranges.
