aWe used potential donors with zero and one dysfunction as a reference to test the effect of the number of organ dysfunctions at the start of the BD investigation of cardiac arrests. For the other variables with more than two categories, each category was compared with the sum of the others
BD brain death, OR odds ratio, CI confidence interval
