Fig 2 Negative linear relationship between ANI and NRS. ANI, analgesia/nociception index; NRS, numerical rating scale. British Journal of Anaesthesia 2014 112, 715-721DOI: (10.1093/bja/aet407) Copyright © 2014 The Author(s) Terms and Conditions
Fig 3 ROC curve showing the relationship between sensitivity (true-positive rate) and 100−specificity (true-negative rate) determining the performance of ANI measured immediately before extubation to predict immediate postoperative pain (NRS>3). The open circle represents Youden index. ANI, analgesia/nociception index; AUC, area under the curve; ROC, receiver-operating characteristic.
