CDAI was a simplified index for assessing the disease activity comprising of the SJC, TJC, PtGA and PGA. CDAI is the numerical sum of 4 outcome parameters: SJC and TJC (based on 28-joint assessment, range from 0 to 28, higher scores meant worse condition), PtGA and PGA (score range from 0 to 10, assessed on 0-10 cm visual analog scale; higher scores indicated greater affection due to disease activity). CDAI total score = 0 (no disease) to 76 (severe disease), higher scores indicated worse condition. Achievement of LDA was defined by CDAI <=10 in participants with moderate or high disease activity CDAI>10 at baseline. Propensity score method was used for analysis of the outcome measure.

HAQ: self-reported, valid assessment of functional disability in RA. The 20-question instrument assessed ability of participants to perform daily activities in 8 functional areas: dressing, arising, eating, walking, reaching, gripping, hygiene, and carrying out daily activities. Eight items were rated on a 4-point Likert scale from 0 to 3, where 0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score ranged from 0 to 3, where 0 = least difficulty and 3 = extreme difficulty, higher scores indicating worse functioning. Propensity score method was used for analysis of the outcome measure.

CDAI was a simplified index for assessing the disease activity comprising of the SJC, TJC, PtGA and PGA. CDAI is the numerical sum of 4 outcome parameters: SJC and TJC (based on 28-joint assessment, range from 0 to 28, higher scores meant worse condition), PtGA and PGA (score range from 0 to 10, assessed on 0-10 cm visual analog scale; higher scores indicated greater affection due to disease activity). CDAI total score = 0 (no disease) to 76 (severe disease), higher scores indicated worse condition. Achievement of LDA was defined by CDAI <=10 in participants with moderate or high disease activity CDAI>10 at baseline. Propensity score method was used for analysis of the outcome measure.
