Infarct size assessed by CMR at six-months was compared across
groups using the Student’s t-test on the log-transformed data with comparison of groups obtained
after back-transformation. Group differences in the median CMR infarct size was also compared
across groups using the Wilcoxon rank sum test. Finally, we used spearman rank correlations to
assess the relationship between cTnI, CK, and CMR infarct size (Supplemental Table 3).
For the primary endpoint we hypothesized that withholding oxygen may influence
