Duodenal and liver iron content in mice fed an iron-adequate or iron-deficient diet.

Data points are wild-type (▪, ■) and Hfe KO (▴, ▵) mice fed iron-adequate (▪, ▴) or iron-deficient (■, ▵) diets. The lines are linear regression fits to data for both diets combined with the following slopes: wild-type (bold line), 0.36 ± 0.09,P < .001, r = 0.643, n = 24;Hfe knock-out (faint line), 0.025 ± 0.007,P < .001, r = 0.551, n = 33. Comparison of regression slopes: P < .001.
