Methods
A systematic literature search was performed in MEDLINE/Pubmed, Embase, the Cochrane Library, Clinical Trials registry, and the Cochrane Central Register of Controlled Trials (CENTRAL). Eligibility criteria were (i) population (studiesinvolving adult patients undergoing surgery or a related intervention); (ii) intervention (intravenous mannitol administered in either the pre- or intra-operative period with comparison to controls); and (iii) predefined outcomes (post-operative AKI or respective renal end points/surrogates).
