Fig. 1From: Psychometric validation and meaningful change thresholds of the Worst Itching Intensity Numerical Rating Scale for assessing itch in patients with chronic kidney disease-associated pruritusEvaluation of meaningful within-patient change on the WI-NRS in exit interviews. a Exit interview M-PGIC responses by WI-NRS change score. b WI-NRS scores by participant response on whether change was clinically meaningful. Participants who reported worsening itch over the trial were not asked if change was or was not meaningful.
