  1. p values refer to the significance of the difference in each CMR parameter between the presence and absence of PGD taking into account all time points, assessed using generalized estimating equations. The significance of the difference in each CMR parameter between the presence and absence of PGD at each individual time point, assessed using independent t tests, is denoted by *(p < 0.05) or (p < 0.01).
