Risk factors analysis

‘Healthy’ BMI, smoking status ‘never’, or no hypertension (absence of hypertension records) were considered as reference values.

Hazard Ratio (HR) values with P < 0.0002 were considered to show significant association with disease onset after correction for multiple-testing using the Bonferroni method

N=154057, Events=319

Factor Level Hazard Ratio P value
BMI overweight 0.95 (0.73, 1.23) 0.691
BMI obese 1.11 (0.83, 1.49) 0.465
BMI underweight 0 (0, Inf) 0.992
smoking previous 1.56 (1.21, 2) 0.00057
smoking current 3.52 (2.62, 4.73) 7.31e-17
hypertension yes 1.28 (1, 1.63) 0.0477
