2. Fig 1
Mean predicted 1-year survival rates of coronary artery bypass graft plus aortic valve replacement by number of risk scores. The risk score was proportionally assigned based on the hazards ratio of significant risk factors in the Cox proportional hazards model shown in Table 5. For the study population, the risk scores ranged between 0 and 12. The bubble plot shows the mean predicted 1-year survival rates by the number of risk scores. The bubble size reflects the actual number of patients associated with their number of risk scores.
