Bernaudin F, Verlhac S, Chevret S, et al. G6PD deficiency, absence of α-thalassemia and hemolytic rate at baseline are significant independent risk factors for abnormally high cerebral velocities in patients with sickle cell anemia. Blood. 2008;112(10):4314–4317.

On page 4315 in the November 15, 2008, issue, in the sixth paragraph of “Results and discussion,” the third sentence contains a minor error that could result in a misinterpretation. The word “less” should have been “more” in the sentence, “Indeed, the trend toward less severe anemia (7.64 vs 7.97 g/dL) in SCA patients with G6PD deficiency (SCA/G6PD) was not significant (P = .19) in our study.” The correct sentence should have read: “Indeed, the trend toward more severe anemia (7.64 vs 7.97 g/dL) in SCA patients with G6PD deficiency (SCA/G6PD) was not significant (P = .19) in our study.”
