Patient number | Sex (M/F) | Age (years) | Transferrin saturation (%) | Serum ferritin concentration (μg/l) | Iron (grade 0–4) | Hepatic iron index (μmol/g/year) |
1 | F | 38 | 77 | 283 | 2 | 3.2 |
2 | F | 31 | 83 | 178 | NLB | NLB |
3 | F | 38 | 71 | 334 | 2 | 7.6 |
4 | F | 20 | 56 | 19 | NLB | NLB |
5 | M | 71 | 95 | 1167 | 3 | 8.0 |
NLB: these patients did not have consistently raised serum ferritin concentrations (patient 2, repeat value 158 μg/l) and did not undergo liver biopsy.
