Fig. 2. Delirium incidence rates and stratifications of SAS score. The delirium incidence rates are higher in higher stratification of SAS score, and the incidence of delirium incrementally increased with stratification of SAS score.
Fig. 3. Predictive value of SAS score for incidence of delirium following OPCABG under ROC. The area under ROC was the area under ROC was 0.934 (95%CI, 0.907-0.960, P<0.001).
