The scale ranged from 0-100 mm, where 0 indicated no disease activity (symptom free and no arthritis symptoms) and 100 represented maximum disease activity (maximum arthritis disease activity).

  12. Change From Baseline in Self-assessment of Pain Based on Visual Analog Scale (VAS) Score at Day 84

    Time frame: Baseline, Day 84

    The participants were asked to assess their level of pain by marking a vertical tick on a 100 mm horizontal VAS scale. The scale ranged from 0-100 mm, where 0 indicated no pain and 100 indicated worst possible pain.

  13. Change From Baseline in Self-assessment of Disability Using Health Assessment Questionnaire - Disability Index (HAQ-DI) Score at Day 84

Scores for each functional area were averaged to calculate HAQ-DI scores, which ranged from 0 (no disability) to 3 (worst disability). A decrease in HAQ-DI score indicated an improvement in the participant's condition.

  14. Change From Baseline in Physician's Global Assessment of Disease Activity Scale Based on Visual Analog Scale (VAS) Score at Day 84

    Time frame: Baseline, Day 84

    The Physician's Global Assessment of Disease Activity was recorded using the 100 mm horizontal VAS.
