Adjusted CI-AKI mortality risk is attenuated versus unadjusted; confirms confounding and leaves causality open for trials.
Does contrast-induced acute kidney injury increase the risk of mortality and adverse clinical outcomes in patients undergoing coronary angiography?
Contrast-induced acute kidney injury after coronary angiography is associated with increased mortality and adverse outcomes, though much of the mortality risk is attributable to baseline confounding factors.
James et al. (2013) studied this question.
