Preoperative patient characteristics and intraoperative and postoperative clinical and surgical variables were recorded, and creatinine clearance (CRCl) was calculated for the preoperative and postoperative periods; renal dysfunction was prospectively defined as a 25% reduction in CRCl.
Odds ratios with 95% confidence intervals (CI) were calculated for each preoperative risk factor.
The criteria for cognitive dysfunction are based on difference scores calculated for each test by subtracting the preoperative test performance from the postoperative test performance at 1 day.
Blood loss was calculated from preoperative and postoperative hematocrit.
A preoperative stroke risk index was calculated for each patient.
A preoperative mortality risk index was calculated for each patient.
To compare the effects of lesions, the difference in performance (trials/reward ratio) between preoperative and postoperative tests was calculated for each monkey.
Presenting the patient's expected WOMAC and EQ-5D outcomes in a boxplot, separated by preoperative scores can facilitate patient choice when preoperative WOMAC and EQ-5D scores are calculated for the patient.
The velopharyngeal area calculated for the Le Fort I osteotomy group showed a significant difference between the preoperative and postoperative measurements.
