Forest plots of raw differences with 99% confidence intervals (CIs) for creatinine (μm/l) along with forest plots of odds ratios (99% CI) for renal replacement therapy and an Acute Kidney Injury Network (AKIN) grade ≥ 1. Each plot reports results for individual studies (McGuiness 2013,28 Haase 2013,29 and Haase 200926 ), combined unadjusted results, combined results with each study treated as a fixed effect, combined results covariate adjusted for attending hospital and baseline imbalances, subgroup analysis stratified by coronary artery bypass graft (CABG), and subgroup analysis stratified by baseline creatinine.
