OR, odds ratio; CI, confidence interval; RR, relative risk; RI, renal insufficiency; MDRD, Modification of Diet in Renal Disease Study; CG, Cockcroft-Gault; CIN, contrastinduced nephropathy. Multivariate analysis was adjusted by covariates such as age, gender, co-morbidities, and kinds of malignancy.
Post-RI MDRD: after CECT, estimated glomerular filtration rate calculated by MDRD equation after CECT <60mL/min/1.73m2. Post-RI CG: after CECT, estimated glomerular filtration rate calculated by CG equation after CECT <60mL/min/1.73m2.
