Trial Outcomes & Findings for Bioequivalence Study With Clinical Endpoint for Diclofenac Sodium Topical Gel 1% (NCT NCT02913521)

NCT ID: NCT02913521

Last Updated: 2021-02-26

Results Overview

WOMAC = Western Ontario and McMaster Universities Arthritis Index. The higher number is more pain. Change from baseline to Week 8 as indicated in the title. Scale is 5 questions with a scale of 0-4, higher number is more pain. Therefore, if you have 5 questions and the max score for each is 4, the maximum number on the scale is 20 (5 questions x 4 units on the scale = 20).
