Forest plots of hospital mortality, 90-day mortality, and survival analysis of time to death. Mortality outcomes are reported as odds ratios (ORs) with 99% confidence intervals (CIs) whilst survival analysis is reported as hazards ratios (HRs) with (99% CI). Results are reported for individual studies (McGuiness 201328 and Haase 201329 ), 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. With only one death per group, results for Haase 200926 have not been reported individually.
