Fig 2 Meta-analysis of postoperative renal outcomes of high-risk patients undergoing coronary artery bypass grafting (CABG). (A) Effects of preoperative prophylactic intraaortic balloon pump (IABP) on the incidence of postoperative acute kidney injury (AKI) in high-risk patients undergoing CABG. (B) Subgroup analysis of the effects of preoperative prophylactic IABP on the incidence of postoperative AKI in high-risk patients undergoing off-pump CABG (OPCABG). (C) Effects of preoperative prophylactic IABP on postoperative renal replacement therapy in high-risk patients undergoing CABG. The solid squares indicate the mean difference and are proportional to the weights used in the meta-analysis. The solid vertical line indicates no effect. The dashed vertical line indicates the summary measure, with the associated diamond indicating the weighted mean difference and the lateral tips of the diamond indicating the associated 95% confidence intervals (CIs). The horizontal lines represent the 95% CI. (OR = odds risk.)
