2. Fig 1
Ratio of estimated versus observed mortality. Patients were divided into three groups based on the logistic EuroSCORE (all patients, high-risk 10 to 20 and excessive risk >20). (AES = additive EuroSCORE; APS = additive Parsonnet score; LES = logistic EuroSCORE; LPS = logistic Parsonnet score; STS = Society of Thoracic Surgeons).
