Model 1: adjusted for age (at incident VTE) and sex.

Model 2: adjusted for age, sex, BMI, and height.

Model 3: adjusted for age, sex, BMI, height, cardiovascular disease (at cohort baseline), and active cancer (at time of VTE diagnosis).

BMI, body mass index; DVT, deep vein thrombosis; HR, hazard ratio; PE, pulmonary embolism; RR, recurrence rate; SHR, subdistribution HR; VTE, venous thromboembolism.

^aRecurrence rate per 100 person-years.

^bDenotes the HR after considering a competing risk by death.
