- Reliability of the European League Against Rheumatism - Rheumatism Arthritis Impact of Disease (EULAR-RAID) Score [ Time Frame: Screening, baseline ]EULAR-RAID score reliability assessed using an intraclass correlation coefficient (using a consistency definition where the between-measure variance is excluded from the denominator variance and its 95% confidence interval) and the standard error of measurement (SEM) and its 95% confidence interval (CI). A higher intraclass correlation coefficient (ICC) indicates greater score reliability (0.0 to 0.10=virtually none; 0.11 to 0.40=slight; 0.41 to 0.60=fair; 0.61 to 0.80=moderate; 0.81 to 1.00=substantial).
- Simplicity: Time for Completion of the EULAR-RAID Questionnaire [ Time Frame: Baseline up to Week 12 ]EULAR-RAID is an assessment of patient reported outcomes for pain, functional disability, fatigue, sleep disturbance, coping, overall assessments of physical well-being and emotional well-being based on 7 numerical rating scales (NRS) questions. NRS individual questions with range of 0 (not affected, very good) to 10 (most affected) weighted and calculated with a total score range of 0 (not affected, very good) to 10 (most affected).
- Face Validity: Correlation Coefficients of the EULAR-RAID Score With the Disease Activity Score Based on 28-joints Count (DAS28) [ Time Frame: Baseline, Week 4 ]DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) and patient's global assessment (PGA) of disease activity (participant rated arthritis activity question measured on an 11-point rating scale scored 0 [none] to 10 [extreme]). Face validity assessed using a correlation coefficient between the EULAR-RAID score and the DAS28. A higher correlation coefficient indicates greater EULAR-RAID score validity.
- Face Validity: Correlation Coefficients of the EULAR-RAID Score With the Disease Activity Score Based on 28-joints Count (DAS28): Week 12 [ Time Frame: Week 12 ]DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, ESR (mm/hour) and patient's global assessment of disease activity (participant rated arthritis activity question measured on an 11-point rating scale scored 0 [none] to 10 [extreme]). Face validity assessed using a correlation coefficient between the EULAR-RAID score and the DAS28. A higher correlation coefficient indicates greater EULAR-RAID score validity.
- Face Validity: Correlation Coefficients of the EULAR-RAID Score With the Disease Activity Score Based on 28-joints Count (DAS28): Time-normalized Average [ Time Frame: Baseline, Last observation up to Week 12 ]Time-normalized average is the area under the curve (AUC) / time between first and last observations. DAS28 calculated from number of swollen joints and painful joints using 28 joints count, ESR (mm/hour) and patient's global assessment of disease activity (participant rated arthritis activity question measured on an 11-point rating scale scored 0 [none] to 10 [extreme]). Face validity assessed using a correlation coefficient between the EULAR-RAID and DAS28 scores. A higher correlation coefficient indicates greater EULAR-RAID score validity.
- Face Validity: Correlation Coefficients of the EULAR-RAID Score With the Patient Global Assessment (PGA) of Health Status [ Time Frame: Baseline, Week 4 ]PGA of health status is a single-item participant rated response to the question "in general, how would you rate your health over the last 2 to 3 weeks"; scored 0 (very well) to 10 (extremely bad). Face validity assessed using a correlation coefficient between the EULAR-RAID score and the PGA. A higher correlation coefficient indicates greater EULAR-RAID score validity (best >0.85).
- Face Validity: Correlation Coefficients of the EULAR-RAID Score With the Patient Global Assessment (PGA) of Health Status: Week 12 [ Time Frame: Week 12 ]PGA of health status is a single-item participant rated response to the question "in general, how would you rate your health over the last 2 to 3 weeks"; scored 0 (very well) to 10 (extremely bad). Face validity assessed using a correlation coefficient between the EULAR-RAID score and PGA health status score. A higher correlation coefficient indicates greater EULAR-RAID score validity (best >0.85).
- Face Validity: Correlation Coefficients of the EULAR-RAID Score With the Patient Global Assessment (PGA) of Health Status: Time-normalized Average [ Time Frame: Baseline, Last observation up to Week 12 ]Time-normalized average is the area under the curve (AUC) / time between first and last observations. PGA of health status is a single-item participant rated response to the question "in general, how would you rate your health over the last 2 to 3 weeks"; scored 0 (very well) to 10 (extremely bad). Face validity assessed using a correlation coefficient between the EULAR-RAID score and PGA health status score. A higher correlation coefficient indicates greater EULAR-RAID score validity (best >0.85).
- Sensitivity to Change of the EULAR-RAID Score: Change From Baseline to Week 4 [ Time Frame: Baseline, Week 4 ]Sensitivity to change analyzed by testing if the difference of change from baseline of EULAR-RAID score minus the change from baseline of each component (pain, functional disability, fatigue, sleep disturbance, coping, overall physical and emotional well-being with score range 0 [not affected, very good] to 10 [most affected]) was different from 0 or not. Results expressed as standardized response mean (SRM) calculated as ratio of mean change over standard deviation of the change. A non significant test (p value ≥0.05) means the component had a significant influence to global EULAR RAID score.
- Sensitivity to Change of the EULAR-RAID Score: Change From Baseline to Week 12 [ Time Frame: Baseline, Week 12 ]Sensitivity to change analyzed by testing if the difference of change from baseline of EULAR-RAID score minus the change from baseline of each component (pain, functional disability, fatigue, sleep disturbance, coping, overall physical and emotional well-being with score range 0 [not affected, very good] to 10 [most affected]) was different from 0 or not. Results expressed as standardized response mean (SRM) calculated as ratio of mean change over standard deviation of the change. A non significant test (p value ≥0.05) means the component had a significant influence to global EULAR RAID score.
- Percentage of Participants Achieving a Moderate or Good EULAR Response Rate at Week 12 [ Time Frame: Week 12 ]EULAR response rate is based on DAS28. For DAS28 ≤3.2 at observation (low disease activity), change from baseline of <-1.2=good response or ≥-1.2 to <-0.6=moderate response; DAS28 >3.2 to 5.1 at observation (moderate or high disease activity), change from baseline of <-1.2 or ≥-1.2 to <-0.6=moderate response; DAS28 >5.1 (high disease activity) at observation, change from baseline of <-1.2=moderate response. DAS28 calculated using the 28 joints count, ESR mm/hour, and PGA of disease activity (participant rated arthritis activity measured on 11-point rating scale: 0 [none] to 10 [extreme]).
- Minimal Clinically Important Improvement (MCII) of the EULAR-RAID Score: 75th Percentile of Change at Week 4 and Week 12 [ Time Frame: Week 4, Week 12 ]MCII is a 2-question assessment of how rheumatoid arthritis has affected the participant in the last 48 hours. Question 1: in comparison to study start (Improved, No Change, or Worse). Question 2: if response was Improved, participant rated how important the improvement was (Very important, Moderately important, Slightly important, or Not important at all). The MCII score is defined as the 75th percentile of the change in EULAR-RAID score between baseline and observation among participants whose evaluation of the response therapy at observation was Moderately or Slightly important improvement.

Question 1: in comparison to study start (Improved, No change, or Worse). Question 2: if response was Improved, participant rated how important the improvement was (Very important, Moderately important, Slightly important, or Not important at all). MCII score at Week 4 calculated on participants with Moderately or Slightly important improvement (Mod/Slightly Imp Improvement) achieved at observation.
- Percentage of Participants Achieving a Minimal Clinically Important Improvement Score at Week 12 Who Had Moderately or Slightly Important Improvement at Week 4, Week 12, or Last Observation (Last Obs) [ Time Frame: Week 4, Week 12, and Last observation up to Week 12 ]MCII is a 2-question assessment of how rheumatoid arthritis has affected the participant in the last 48 hours.
