The Overall score defined as lowest percent improvement from BL of following 3 measures: TJC (68 joints), SJC (66 joints), and the 3rd lowest improvement achieved by at least 3 of 5 remaining ACR core parameters: physician's global assessment of disease activity, participant's global assessment of disease activity, participant's assessment of pain (VAS), HAQ, and CRP. If CRP missing, ESR was used. In order for improvements in the ACRn score to be expressed as a positive result, rather than the negative changes that improvements represent, the final ACRn results were multiplied by negative 1. LOCF for TJC/SJC, HAQ, CRP/ESR, VAS. If change in CRP incalculable, change in ESR used. ACR70 set to Non-Responder if ACRn missing.","groups":[{"description":"Participants received rituximab, 0.5 g, IV, on Days 1, 15, 168, and 182.
