Calibration of cardiac R2* with CIC assessed in EMBs. The figure displays the relationship of cardiac R2* (= 1/T2*) to CIC. Non-parametric regression analysis (Passing and Bablok) led to the calibration equation [CIC] = (R2* − 17.16/41.12 with CIC in mg/g DW and R2* in Hz. The total number of parallel cardiac R2* and chemical CIC measurements was 55. Solid line is the regression line and dotted lines display its confidence interval. ULN for cardiac R2* is 28.18 Hz and ULN for CIC 0.31 mg Fe/g DW
