Fig 1 Distribution of cases by Aristotle comprehensive complexity score (CCS) category for each institution (Inst). Aristotle comprehensive complexity score categories are defined in the text and in Table 5.

Fig 2 Receiver operating characteristic curves for the logistic regression of mortality, for institution 1 (A) and institution 2 (B). The corresponding C statistics are displayed in Table 3. (BCS = Aristotle basic complexity score; CCS = Aristotle comprehensive complexity score; RACHS = Risk Adjustment in Congenital Heart Surgery.)
