Correlation between conjugated diene lipid hydroperoxides in LDL (LDL-CD) and the amounts of vitamin E in plasma (A) and in LDL (B) from β-thalassemia intermedia patients. Each blood sample was simultaneously processed for isolating and analyzing LDL and for the analysis of plasma vitamin E (n = 35; A: r = −.659; P < .0001; B: r = −.784; P < .0001).
