All bold differences between PET pairs defined by the columns and rows are significant with p ≤ 0.022 indicating that their differences listed in the table are significant where a positive sign indicates a higher value on PET2 than PET1 and a negative sign indicates a lower value on PET2 than on PET1. Outside the bold cells, no differences are significant; italics indicate a substantial negative difference with a lower value on PET2 that, however, is not significantly different.
PET = positron emission tomography.
