| MIC | Cardiac T2*MRI, ms * | −0.802** | 0.001 |
| MIC | LIC mg/g/dry weight | −0.096 | 0.557 |
| LVEF | SF | 0.132 | 0.416 |
| LVEF | Cardiac T2*MRI, ms | −0.103 | 0.525 |

Notes: *Correlation is significant at the 0.05 level (2-tailed). **Correlation is significant at the 0.01 level (2-tailed).
Abbreviations: MIC, myocardial iron concentration; LIC, liver iron concentration; MRI, magnetic resonance imaging; ms, miliseconds; SF, serum ferritin.
