Table cells express results in for normally distributed continuous variables, (%) for dichotomous variables, and median (interquartile range) for ordinal variables and nonnormally distributed continuous variables, respectively. The DWI volume of the infarct core has been acquired on ADC maps () and the volume of PWI on maps.
