Fig 1 Five-year readmission: time is plotted from alive cardiac surgery discharge to first readmission to any hospital stratified by Acute Kidney Injury Network (AKIN) stage: no acute kidney injury (AKI [blue line]); AKIN stage 1 (red line); and AKIN stage 2 or 3 (green line). Log rank test χ2 46.43, p < 0.001. The Annals of Thoracic Surgery 2016 102, 1482-1489DOI: (10.1016/j.athoracsur.2016.04.020) Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions
Fig 2 Five-year mortality: time is plotted from alive cardiac surgery discharge to all-cause death stratified by Acute Kidney Injury Network (AKIN) stage: no acute kidney injury (AKI [blue line]); AKIN stage 1 (red line); and AKIN stage 2 or 3 (green line).

Fig 4 Reasons for hospital readmission. Pareto chart depicts the reasons for readmission in our cohort. The category “other,” accounting for 2.5% of readmissions, is not included in this chart. Green line indicates cumulative percentage of readmissions; black bars indicate number of readmissions in the cohort.
