The 'overall activity impairment due to health problem' was assessed using the WPAI-GHP questionnaire. WPAI-GHP is a six-item participant-assessed questionnaire used to assess work and activity impairment due to symptoms of rheumatoid diseases (RA, PsA, and AS). The 'overall activity impairment due to health problem' was calculated based on one item: (Q6) to what degree did the disease impair the ability to do regular activities in the past seven days from visit. The item was measured on a scale from 0 (no effect) to 10 (completely prevented from doing regular activities/working). The data was calculated using the formula Q6/10 and converted to percent. Data are presented as impairment percentage, with higher numbers indicating greater impairment and less productivity.

WPAI-GHP is a six-item participant-assessed questionnaire used to assess work and activity impairment due to symptoms of rheumatoid diseases (RA, PsA, and AS). The 'impairment while working due to health problem' was calculated based on one item: (Q5) to what degree did the disease impair the productivity while working in the past seven days from visit. The item was measured on a scale from 0 (no effect) to 10 (completely prevented from doing regular activities/ working). The data was calculated using the formula Q5/10 and converted to percent. Data are presented as impairment percentage, with higher numbers indicating greater impairment and less productivity.

The 'overall work impairment due to health problem' was assessed using the WPAI-GHP questionnaire. WPAI-GHP is a six-item participant-assessed questionnaire used to assess work and activity impairment due to symptoms of rheumatoid diseases (RA, PsA, and AS). The 'overall work impairment due to health problem' was calculated based on three items: (Q2) the number of hours missed from work due to health problems in the past seven days from visit; (Q4) the number of actual work hours in the past seven days from visit; and (Q5) to what degree did the disease impair the productivity while working past seven days from visit). The data was calculated using the formula Q2/(Q2+Q4)+[(1-(Q2/(Q2+Q4))x(Q5/10)] and converted to percent. Data are presented as impairment percentage, with higher numbers indicating greater impairment and less productivity.

The DAS28, a combined index that measured rheumatoid arthritis disease activity, was calculated based on: (1) the number of tender joints among 28 joints evaluated; (2) the number of swollen joints among 28 joints evaluated; (3) general health evaluated by a visual analog scale (VAS); (4) erythrocyte sedimentation rate (ESR); and (5) C-reactive protein (CRP). The DAS28 scores ranged from 0 (no disease activity) to 10 (maximal disease activity); decrease in DAS28 scores indicate improvement of disease. The DAS28 score less than or equal to 2.6 is defined as clinical remission. Data are presented as mean DAS28 score +/- standard deviation.

The HAQ-DI was a participant-reported questionnaire that measured quality of life in terms of physical function of participants with rheumatoid arthritis. It consisted of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past seven days using the following response categories (score): without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). The scores on each task were summed and averaged to provide an overall score from 0 to 3, where 0-1 represented mild disability and 2-3 represented severe disability. Data are presented as mean HAQ-DI score +/- standard deviation.

The BASDAI was a six question, participant-reported measure of overall disease activity that probed the level of fatigue, neck/back/hip pain, peripheral joint swelling and pain, localized tenderness, as well as morning stiffness severity and duration. The mean measurement (score) of questions 5 and 6 is added to the scores from questions 1 to 4 and divided by 5 to calculate the total BASDAI score. It was scored on a numerical rating scale that ranged from 0 (no symptoms) to 10 (severe symptoms), higher scores indicating severe disability due to AS disease. Data are presented as mean total BASDAI score +/- standard deviation.

As the patient and physician global assessments were performed using a 0-100 VAS scale instead of the 5 point Likert scale, the PsARC score could not be calculated, although data on joint pain and swelling were collected. Hence, the psoriatic arthritis disease activity was evaluated by the percentage of patients with tender and swollen joints, acute phase reactants (ESR and CRP), and VAS Score (patient and physician). Data are reported under outcome measures 13 through 16.

Joints (68 or 66) were assessed by pressure and joint manipulation on physical examination for TJC or SJC, respectively. Both joint tenderness and swelling were classified as present ("1"), absent ("0"), replaced ("9"), or no assessment ("NA"). The total TJC or SJC was derived as the sum of the tender and swollen joints; the range for TJC and SJC were 0 - 68 and 0 - 66, respectively with higher scores indicated worse conditions. Data are presented as percentage of participants with TJC and SJC.

Plasma concentrations were assessed to evaluate ESR, a marker of systemic inflammation that provided insights into the overall anti-inflammatory effect of rheumatologic therapies. Data are presented as mean ESR value in millimeters per hour (mm/hr) ± standard deviation.

Plasma concentrations were assessed to evaluate CRP, a marker of systemic inflammation that provided insights into the overall anti-inflammatory effect of rheumatologic therapies. Data are presented as mean CRP value in milligrams per liter (mg/L) ± standard deviation.

The VAS score assessed by participants (pt) and physicians (ph) was used to determine the pain due to psoriatic arthritis in the past week. The level of pain was measured in millimeters (mm) on a 100 mm horizontal line. The score ranged from 0 (no pain) to 100 (severe pain). Data are presented as mean VAS score +/- standard deviation.

The Medical Outcome Study (MOS) sleep scale was a 12-item, participant-reported, non-disease-specific measure related to sleep that yielded 7 subscales (4-item sleep disturbance, 2-item sleep adequacy, 1-item quantity of sleep, 3-item somnolence, 1-item snoring, 1-item shortness of breath, and 9-item overall sleep problems index). Only sleep disturbance subscale was assessed by calculating the average of the 4-items with total score ranging from 0 to 100 (higher scores indicating greater sleep disturbance). Data are presented as mean score on a scale +/- standard deviation.

The 'work time missed due to health problem' was assessed using the Work Productivity and Activity Impairment-General Health Problem (WPAI-GHP) questionnaire. WPAI-GHP is a six-item participant-assessed questionnaire used to assess work and activity impairment due to symptoms of rheumatoid diseases (RA, PsA, and AS). The 'work time missed due to health problem' was calculated based on two items: (Q2) the number of hours missed from work due to health problems in the past seven days from visit and (Q4) the number of actual work hours in the past seven days from visit. The data was calculated using the formula Q2/(Q2+Q4) and converted to percent. Data are presented as impairment percentage, with higher numbers indicating greater impairment and less productivity.

The analysis was performed using efficacy analysis set defined as all participants in the enrolled population with an available WPAI-GHP score at the study time points.
