Fig. 2From: Translation, cross-cultural adaptation and psychometric properties of the Nepali versions of numerical pain rating scale and global rating of changeReceiver operating characteristic (ROC) curves.ᅟa Receiver Operating Characteristic (ROC) Curve for the stable group (GROC=4) versus improved group (GROC=5-7). Area under this curve (AUC) indicates the accuracy of NPRS-NP for differentiating between the stable and improved group with the value of AUC closer to “1” indicating better agreement with the GROC-NP as an external anchor. b Receiver Operating Characteristic (ROC) Curve for small improvement group (GROC=5). Area under this curve (AUC) indicates the accuracy of NPRS-NP for differentiating between the stable group and the group that had a small improvement with the value of AUC closer to “1” indicating better agreement with the GROC-NP as an external anchor. c Receiver Operating Characteristic (ROC) Curve for the medium improvement group (GROC=6). Area under this curve (AUC) indicates the accuracy of NPRS-NP for differentiating between the stable group and the group that had a medium improvement with the value of AUC closer to “1” indicating better agreement with the GROC-NP as an external anchor. d Receiver Operating Characteristic (ROC) Curve for the large improvement group (GROC=7). Area under this curve (AUC) indicates the accuracy of NPRS-NP for differentiating between the stable group and the group that had a large improvement with the value of AUC closer to “1” indicating better agreement with the GROC-NP as an external anchorBack to article page
