*Some studies did not collect temporary interruption of study drug.
†Used EAIR per 100 PY (patient exposure not censored at the event).
‡Potential CV adverse events from the phase III and LTE trials, identified by investigators or according to a predefined list of event terms, were adjudicated by an independent, external Clinical Endpoint Committee that remained blinded to treatment assignments.
§DVT includes distal events below the knee.
AE, adverse events; bari, baricitinib; CV, cardiovascular; DVT, deep vein thrombosis; EAIR, exposure-adjusted incidence rate; GI, gastrointestinal; IR, incidence rate; LTE, long-term extension; MACE, major adverse cardiovascular events; MI, myocardial infarction; N, number of patients in the analysis set; n, number of patients in the specified category; NMSC, non-melanoma skin cancer; PE, pulmonary embolism; PY, patient-years; RA, rheumatoid arthritis; SAE, serious adverse event; TB, tuberculosis; TEAE, treatment-emergent adverse event.
