Number of Participants With Biochemistry Parameters Values Falling Within Reference Values at Visit 1

时间窗: At Visit 1

Biochemistry parameters is considered as one of the component of clinical characteristics. Biochemistry parameters included alanine amino transferase (ALT), aspartate amino transferase (AST), triglycerides, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), and total lipids.

Number of Participants With Smoking Habits

时间窗: At Visit 1

Smoking habits is a component of socio-demographic characteristics. Participants' smoking status is recorded as non-smoker, smoker, and ex-smoker at Visit 1.

Mean Time of Onset of Rheumatoid Arthritis

时间窗: At Visit 1

Onset of rheumatoid arthritis is a component of clinical characteristics.

Mean Number of Painful and Swollen Joints at Visit 1

时间窗: At Visit 1

Participants were assessed for painful and swollen joints at Visit 1. Painful joint is the most specific clinical method to quantify abnormalities in participants with RA. It reflects the amount of inflamed synovial tissue.

Mean Score on Disease Activity Score Based on 28-Joints Count at Visit 1

时间窗: At Visit 1

Disease activity score (DAS) 28 is a combined index for measuring disease activity in RA. The index includes swollen (range 0-28) and tender (range 0-28) joint counts, acute phase response (ESR in mm/hr), and general health status (participant global assessment of disease activity using VAS, range 1-100 mm). DAS28, which uses a 28-joint count, is derived from the original DAS, which includes a 44-swollen joint count. The DAS28 scale ranges from 0 to 10, where higher scores indicate worsening.

Number of Participants With Clinical Disease Activity by Categorization at Visit 1

时间窗: At Visit 1

CDAI is divided into 4 categories as: remission \<2.8, low activity 2.8-10, moderate 10-22 and high\>22.

Number of Participants With Extra-articular Manifestations at Visit 1

时间窗: At Visit 1

Extra-articular manifestations (EAMs) are a component of of clinical characteristics EAMs are symptoms and diseases that occur in parts of the body other than joints. These included the presence of amyloidosis (rare disease that results from the buildup of misfolded proteins), anemia (deficiency of red cells in the blood), heart complications, lung complications, rheumatoid nodules (local swelling), felty's syndrome (presence of rheumatoid arthritis, an enlarged spleen, and an abnormally low white blood cell count), and secondary Sjogren's (an autoimmune disorder that damages moisture-producing glands, making it difficult to produce saliva and tears). Participants were assessed into categories with extra-articular Manifestations as yes, no and missing nos.

Number of Participants With Presence/Absence Rheumatoid Factor and Anti-Cyclic Citrullinated Protein Antibodies

时间窗: At Visit 1

Rheumatoid Factor (RF) is the auto antibody directed against Immunoglobulin G and its concentration is observed in human serum or plasma. Anti-Cyclic Citrullinated Protein Antibodies (Anti-CCP) antibodies are auto antibodies (antibodies directed against 1 or more of an individual's own proteins) that are frequently detected in the blood of rheumatoid arthritis participants.

Mean Score on Simple Disease Activity Index at Visit 1

时间窗: At Visit 1

Simple Disease Activity Index (SDAI) is calculated by sum of number of painful joint and swollen joint count, patient and physician global assessment of disease activity (VAS 0-10 cm), and level of C-reactive protein in milligrams per deciliter (mg/dL). SDAI total score ranges from 0 to 86, where higher scores indicates greater affect due to disease activity.

Patient's Global Assessment of Disease Activity at Visit 1

时间窗: At Visit 1

Patient global assessment of disease activity visual analog scale is assessed using a 0 to 100 mm horizontal VAS. The left-hand extreme of the line equals 0 mm, and is described as "no disease activity" (symptom-free and no arthritis symptoms) and the right-hand extreme equals 100 mm, as "maximum disease activity" (maximum arthritis disease activity).

Patient Pain Visual Analog Scale Score at Visit 1

时间窗: At Visit 1

Participants assessed their pain using a 0 to 10 horizontal visual analogue scale (VAS). The left-hand extreme of the line equals 0 and is described as "no pain" and the right-hand extreme equals 10 as "unbearable pain"

Number of Participants With Disease Activity Score by Categorization at Visit 1

时间窗: At Visit 1

DAS28 is divided into 4 categories as: remission \<2.6, low activity 2.6-3.2, moderate 3.2-5.1 and high \>5.1.

Number of Participants With C-reactive Protein and Erythrocyte Sedimentation Rate Falling Within Reference Values at Visit 1

时间窗: At Visit 1

The test for C-reactive Protein (CRP) is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultra-sensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement. Erythrocyte sedimentation rate (ESR) is a laboratory test that provides a non-specific measure of inflammation. A higher rate is consistent with inflammation.
