What was measured

The NRS-11 is a self-reported 11-point numerical scale that assesses pain severity. Participants ≥ 8 years of age are asked to select a number from 0 (no pain) to 10 (worst pain you can imagine) that best describes their worst pain. The recall period is 24 hours. The change from baseline is modelled using a mixed-model for repeated measures.

Analysis population: The Full Analysis Set patients eligible for the instrument at baseline.
