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).
