From: A novel collagen area fraction index to quantitatively assess bowel fibrosis in patients with Crohn’s disease

Fig. 3

On the ROC analysis, the collagen area fraction was slightly more accurate, with an AUC of 0.815 (95% CI = 0.721–0.910, P < 0.001), than the histological fibrosis score (AUC = 0.771; 95% CI = 0.666–0.877; P < 0.001) for diagnosing CD strictures. ROC, receiver operating characteristic; AUC, area under the ROC curve; CD, Crohn’s disease; CI, confidence interval
