Study design details

Main study objective

The main objective of the study is to assess the safety of tofacitinb in the post-approval setting.

Outcomes

The primary outcomes are serious infections, malignancies and cardiovascular events. Secondary outcomes include events commonly seen in patients with RA.

Data analysis plan

For the safety endpoints of interest, summary statistics, frequencies, crude cumulative incidence proportions, and crude incidence rates (ie, number of events per person-years) and associated 95% confidence intervals will be calculated as appropriate. Depending on data availability, subgroupanalyses may be performed.
