Predicting unplanned extubation risk in patients with endoscopic nasobiliary drainage

Figure 3 Logistic regression analysis and receiver operating characteristic curve of risk factors for unplanned nasobiliary tube extubation. This image provides a total assessment of risk factors for unintended extubation of nasobiliary tubes. A: A forest plot of six independent risk factors, including their odds ratios and confidence intervals, among which consciousness change was the riskiest [odds ratio = 3.157], and serum albumin was a protector (odds ratio = 0.91); B: The receiver operating characteristic curve validation that showed a good construct validity with an area under the curve of 0.881 in the training group and 0.865 in the validation group. The model had good discrimination in both studies, and all the risk factors were significant (P < 0.05). The area under the curves was far above the reference line. OR: Odds ratio; CI: Confidence interval; AUC: Area under the curve.
