Intervention: Laboratory tests (examination)
Description: Laboratory tests (examination) to be performed include complete blood count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), liver function tests and kidney function tests; rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (anti-CCP antibody) and C-C Motif Chemokine Ligand 21 (CCL21).

Intervention: Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index
Description: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) This questionnaire is used to assess the health status of osteoarthritis patients introduced in 1988 (13). It is consisted of 33 items which evaluates the health and function of the patient from various aspects including: clinical symptoms (5 questions), severity of joint stiffness (2 questions), degree of pain (9 questions), and activity of daily living (17 questions).The test questions are scored on a scale of 0-4, which correspond to: None(0),Mild (1),Moderate (2),Severe(3),and Extreme (4).The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. Usually a sum of the scores for all three subscales gives a total WOMAC score, however there are other methods that have been used to combine scores.Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.

Intervention: The Disease Activity Score28 (DAS28)
Description: The Disease Activity Score (DAS) was created as a numerical tool for quantifying and assessing disease activity in rheumatoid arthritis (RA).The DAS28 (Disease Activity Score using 28 joint counts) was developed from the original DAS (Disease Activity Score).The DAS28 evaluates the disease activity by assessing the number of tender and swollen joints in a patient. Specifically, it considers 28 joints. The DAS28 also takes into account a blood marker of inflammation, typically the erythrocyte sedimentation rate (ESR) or the C-reactive protein (CRP) level.A patient with a DAS28 score of less than 2.6 is in remission; a score greater than or equal to 2.6 and less than 3.1 indicates low activity; a score greater than or equal to 3.1 and \<5.1 indicates moderate activity and a score 5.1 or more indicates high activity

Intervention type: DIAGNOSTIC_TEST
Intervention: Patient global assessment (PGA)
Description: Patient global assessment (PGA) of disease activity will be reported by patients. PGA was developed in the late 1970s and was initially designed for the measurement of self-assessed pain in RA \[8\], although it has since been used to evaluate RA more globally. It is interesting to note that the way PGA is used in clinical practice covers, in fact, two very different concepts, one related to global health and the other to overall disease activity. They are both usually used under the heading of PGA without further specification for which is being assessed.
