Inclusion Criteria
- At least one claim for tofacitinib between 01 January 2014 and 31 January 2017 (the identification period).
- Presence of The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9 CM) code for RA (in any position) during the one-year pre-index period or on the index date. ICD-9 = 714.0x-714.4x & 714.81 or ICD10 = M05.* & M06.0*-M06.3* or M06.8*-M06.9*.

Exclusion Criteria
- Patients with claims for other conditions for which biologics are used during the one-year pre-index period or on the index date: ankylosing spondylitis, Crohn's disease, psoriasis, psoriatic arthritis, or ulcerative colitis will be excluded from the study.
- Patients with evidence of the index medication during the one-year pre-index period will be removed from the analysis. Patients will be allowed to have been treated with other biologics approved for RA (Tumor-Necrosis Factor-alpha inhibitors (TNFi) [adalimumab (Humira), etanercept (Enbrel), certolizumab pegol (Cimzia), golimumab (Simponi), infliximab (Remicade)] and non-TNFi's with alternative mechanisms of action [abatacept (Orencia), and rituximab (Rituxan), anakinra (Kineret), tocilizumab (Actemra)]) during the one-year pre-index period.
