  1. ICU patients were without intraoperative hypotension (MAP < 65 mmHg) and are stratified by postoperative MAP level (≤ 75, ≤ 65 and ≤ 55 mmHg). Primary and secondary outcomes are shown.
  2. AIS, acute ischemic stroke; AKI, acute kidney injury; AMI, acute myocardial infarction; MACCE, major adverse cardiac and cerebrovascular events; MAP, mean arterial pressure. CRRT, continuous renal replacement therapy. AMI and AIS were captured using ICD 9/10 codes (see Additional file 1: Table S2, for ICD codes). AKI stage II/III was defined using the following definition: postoperative creatinine two times greater than the most recent preoperative value, an increase in serum creatinine ≥ 4 mg/dL, or initiation of dialysis therapy
