The intervention group is subdivided in donors and transplants treated per protocol and those prematurely withdrawn from the infusion for side effects or not given dopamine despite randomization to treatment. ICU, intensive care unit; IQR, interquartile range; n.e., not estimable; —, not applicable.
Last assessment before organ procurement.
Not estimable in five donors not given dopamine.
