Disentangling true inspection time from therapeutic intervals: Validation of effective withdrawal time as a colonoscopy quality metric

Figure 3 Comparative predictive performance of withdrawal times for lesion detection. A: Receiver operating characteristic (ROC) curve for polyp detection using the continuous model, comparing effective withdrawal time (EWT) (orange) and standard withdrawal time (SWT) (blue); B: ROC curve for polyp detection using the quintile model, comparing EWT (orange) and SWT (blue); C: ROC curve for adenoma detection using the continuity model, comparing EWT (orange) and SWT (blue); D: ROC curve for adenoma detection using the quintile model, comparing EWT (orange) and SWT (blue); E: ROC curve for colorectal cancer detection using the continuity model, comparing EWT (orange) and SWT (blue); F: ROC curve for colorectal cancer detection using the quintile model, comparing EWT (orange) and SWT (blue). EWT: Effective withdrawal time; SWT: Standard withdrawal time; AUC: Area under the curve.
