Construction of a risk prediction model for postoperative gastrointestinal dysfunction and prevention in patients with gastrointestinal tumors

Table 3 Receiver operating characteristic curve analysis results of the risk prediction model for postoperative gastrointestinal dysfunction in patients with gastrointestinal tumors

Index	AUC	95%CI	P value	Optimal cut-off value	Sensitivity (%)	Specificity (%)
Prediction model	0.895	0.842-0.948	0.000	0.456	82.3	85.6

Optimal cut-off value represents the threshold value with the best balance of sensitivity and specificity; Sensitivity represents true positive rate; Specificity represents true negative rate. P < 0.05 was considered statistically significant. AUC: Area under the receiver operating characteristic curve; 95%CI: 95% confidence interval.
