Interpretation of equivalence of tested hematocrits (Hct1, Hctsyn) to the standard hematocrit (Hct0) for ECV measurements. The dashed vertical lines indicate the predefined equivalence margins (− 2 to 2%) and the horizontal lines represent the 95% confidence interval (CI) of the difference in ECV between compared Hcts. Equivalence is concluded if the entire CI is within the equivalence margins. Hct1 [conv] and Hct1 [inline] are hematocrits obtained on a different day from that of CMR f using the conventional and inline ECV methods, respectively. Hctsyn [conv] and Hctsyn [inline] are Hcts obtained synthetically from native blood T1 mapping using the conventional and inline ECV methods, respectively
