Fig. (2) The Receiver operating characteristic (ROC) discrimination curve of prediction models for CRSsNP group (n=55) over CRSwNP group (n=18). Total radiologic NP score gave an AUROC of 0.95 (95% CI 0.91-1.00), p<0.001. With the threshold value total radiologic NP score ≥ 8/16, the sensitivity was 94% and specificity 82% for detecting CRSwNP from CRSsNP group. Total LM score gave an AUROC of 0.84 (95% CI 0.75-0.94), p<0.001. With the threshold value LM score ≥ 9/24 the sensitivity was 78% and specificity 69% for detecting CRSwNP from CRSsNP group.
