Using the preoperative and intraoperative information of another patient in the model: age: 44 years, albumin: 36.5 g/L, ASTI: 4 days, CRP: 1.23 mg/L, IBL: 100 ml, IMBP: 110 mmHg, AIMBPD: 41 mmHg, smoking: No, alcohol: No, PD: No, hypertension: Yes, CCD: No, the predicted probability of POD in this patient was 3.992%, indicating that the patient was at low risk of developing POD (Figure 8B). This evidence concerns the gene ALB and hypertensive disorder.
