ROC curves for patient self-administration of an opioid bolus (trial III). OR-SDS, opioid symptom distress score; OBAS, overall benefit of analgesia score; BPI, average pain intensity score of the modified brief pain intensity score (short form); ROC, receiver operator characteristics. Note that the AUCs of the OBAS and BPI are higher compared with the OR-SDS.

3. Fig 2
Relations between patients’ satisfaction with postoperative analgesia and the OBAS, the OBAS without the criterion patients’ satisfaction, and pain scores at rest and during movement. The OBAS and the modified OBAS but not pain scores correlate significantly with patients’ satisfaction with postoperative analgesia. (a and b), comparison between OBAS and patient satisfaction; (c and d), comparison between pain scores and patient satisfaction.
