OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline up to Week 16

Population: The safety analysis population included randomized participants who received at least 1 dose of the study drug (tofacitinib or placebo).

An AE was any untoward medical occurrence in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to Week 16 that were absent before treatment or that worsened relative to pre-treatment state. AEs included both SAEs and non-SAEs.
