  • *Includes patients who had valid D-dimer measurement at baseline and excludes patients who used anticoagulants at baseline (aspirin use was permitted). VTE events were within the 28-day on-treatment risk period.

  • †For patients assigned to receive tofacitinib at a dose of 10 mg two times per day who had their dose reduced to 5 mg two times per day, the data collected after patients had been switched to 5 mg two times per day were counted in the arm receiving 10 mg two times per day.

  • BMI, body mass index; DVT, deep vein thrombosis; HDL-C, high-density lipoprotein cholesterol; HRT, hormone replacement therapy; N, number of patients in each treatment arm in the biomarker subpopulation; n, number of patients meeting baseline criteria; PE, pulmonary embolism; TNFi, tumour necrosis factor inhibitor; VTE, venous thromboembolism.
