Fig. 3(a).
HC vs C for hemoglobin, myoglobin, and ferritin concentration models. SD of HC is 80, 83, 2400, and 2940 for hemoglobin, myoglobin, ferritin 1, and ferritin 2 models. The straight lines represent a linear regression of the measured data for each model (R2 = 0.092, 0.178, 0.433, 0.117, with slope 66, −88, −5431, −4975 and intercept 604, 1170, 152738, 289016).

MR vs C for hemoglobin, myoglobin, and ferritin concentration models. SD of MR is 4.6 × 10−6, 5.1 × 10−6, 5.5 × 10−4, and 5.4 × 10−4 for hemoglobin, myoglobin, ferritin 1, and ferritin 2 models. The lines are a linear regression of the measured data for each model (R2 = 0.943, 0.979, 0.974, 0.970 with slope 8.5 × 10−5, 1.9 × 10−4, 9.6 × 10−2, 11.3 × 10−2 and intercept 1.4 × 10−5, 2.58 × 10−5, 1.6 × 10−2, 2.2 × 10−2).

Dependence of MMAX vs C for hemoglobin, myoglobin, and ferritin concentration models. SD of MMAX is 9.6 × 10−3, 8.6 × 10−3, 1.6 × 10−3, and 1.8 × 10−3 for hemoglobin, myoglobin, ferritin 1, and ferritin 2 models. Lines are a linear regression of measured data for each model (R2 = 0.978, 0.986, 0.987, 0.980 with slope 17.1 × 10−2, 23.5 × 10−2, 1.67, 0.95 and intercept 3.5 × 10−2, 3.6 × 10−2, 15.0 × 10−2, 13.9 × 10−2).
