<p>(A) Total phospholipids: n = 23 (case) and n = 14 (control), p = 0.013 (Student's t test). (B) Total phospholipids of patients with iron overload, stratified by age: n = 11 (<50 years) and n = 12 (> = 50 years), p = 0.554 (Student's t test). (C) Total membrane cholesterol: n = 23 (case) and n = 14 (control), p<0.001 (Student's t test). (D) Total membrane cholesterol of patients with iron overload, stratified by age: n = 11 (<50 years) and n = 12 (> = 50 years), p = 0.241 (Student's t test). All experiments were performed in triplicate and the line in bars represented the mean and the error bar denotes SEM.</p
