the bournemouth scoring system identified 3 risk groups , a ( 0-1 points ) , b ( 2-3 points ) and c ( 4 points ) , in the whole series ( p less than 0.0001 ) and it allowed us to stratify refractory anemia ( ra ) , ra with excess of blasts ( raeb ) and raeb in transformation ( raeb-t ) patients into two distinct prognostic groups ( p = 0.03 and p = 0.01 , respectively ) .
