Scatter plots of total iron removed versus serum ferritin (SF) concentration.
 SF values are those at clinical evaluation, with linear regression line among (a) the C282Y homozygote men who completed the quantitative phlebotomy program (N = 39, R² = 0.35, P < .0001) and (b) C282Y homozygote women who completed the quantitative phlebotomy program (N = 37, R² = 0.29, P = .0006).
