Table 4.

Evaluation metrics of the reperfused and non-reperfused models after successive ablation of the MRI inputs, tested among (a) reperfused and (b) non-reperfused patients, respectively (average values ± standard deviation). Bold values correspond to the best value of the respective evaluation metric (column-wise). A two-sided wilcoxon signed-rank test was performed between the full models with all 5 MRI inputs and the ablated ones, with (.) indicating P < 0.10, (*) indicating P < 0.05, (**) indicating P < 0.01 and (***) indicating P < 0.001.
