BMI was calculated by weight divided by height squared and measured as kilogram per square meter (kg/m\^2).

Blood Pressure (BP)

时间窗: Baseline

BP is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. BP measurement is recorded by 2 numbers: systolic BP (SBP, BP when heart is contracting; it is the maximum arterial pressure during contraction of left ventricle) and diastolic BP (DBP, BP when heart is relaxing; it is the minimum arterial pressure during relaxation and dilation of ventricles).

Change From Baseline in Disease Activity Score Based on 28-joints Count (DAS28) at Month 60

时间窗: Baseline, Month 60

DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, acute phase reactants (erythrocyte sedimentation rate \[ESR, millimeters per hour\] or C-reactive protein \[CRP, milligram per liter\]) and patient's global assessment (PtGA) of disease activity (participant rated arthritis activity assessment with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity). DAS28 \<2.6: remission, DAS28 \<=3.2: low disease activity, DAS28 \>3.2 to \<=5.1: moderate disease activity, DAS28 \>5.1: progression.

Change From Baseline in Tender Joints Count (TJC) at Month 60

时间窗: Baseline, Month 60

Number of tender joints was determined by examining 28 joints and identified the joints that were painful under pressure or to passive motion. The number of tender joints was recorded on the joint assessment form at each visit, no tenderness = 0, tenderness = 1. A negative value in change from baseline indicates an improvement.

Change From Baseline in Swollen Joints Count (SJC) at Month 60

时间窗: Baseline, Month 60

Number of swollen joints was determined by examination of 28 joints and identifying when swelling was present. The number of swollen joints was recorded on the joint assessment form at each visit, no swelling = 0, swelling =1. A negative value in change from baseline indicates an improvement.

Change From Baseline in C-Reactive Protein (CRP) Level at Month 60

时间窗: Baseline, Month 60

The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultra-sensitive assay. Normal range of CRP is \<10 milligram/liter (mg/L). A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.

Change From Baseline in Erythrocyte Sedimentation Rate (ESR) at Month 60

时间窗: Baseline, Month 60

ESR is a laboratory test that provides a non-specific measure of inflammation. The test assesses the rate at which red blood cells fall in a test tube. Normal range is 0-30 millimeter/hour (mm/hr). A higher rate is consistent with inflammation.

Change From Baseline in Patient's Global Assessment (PtGA) of Disease Activity at Month 60

时间窗: Baseline, Month 60

Participants answered: "Considering all the ways your arthritis affects you, how are you feeling today?" Participants responded by using a 0 - 100 mm VAS, where 0 mm = very well and 100 mm = very poorly.

Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) Score at Month 60

时间窗: Baseline, Month 60

Health Assessment Questionnaire-Disability Index (HAQ-DI): participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0 = no difficulty; 1 = some difficulty; 2 = much difficulty; 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 range 0 to 3 where 0 = least difficulty and 3 = extreme difficulty.

Change From Baseline in 36-Item Short-Form Health Survey (SF-36) at Month 60

时间窗: Baseline, Month 60

The 36-Item Short-Form Health Survey (SF-36) is a standardized survey evaluating 8 aspects of functional health and well-being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health. These 8 aspects can also be summarized as physical component score (PCS) and mental component score (MCS). Total of 3 variables were analyzed (2 composite subscales and vitality score). The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning).

Change From Baseline in Euro Quality of Life - 5 Dimensions (EQ-5D) at Month 60

时间窗: Baseline, Month 60

EQ-5D: participant rated questionnaire to assess health-related quality of life in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state (confined to bed). Scoring formula developed by EuroQoL Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range -0.594 to 1.000; higher score indicates a better health state.
