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=153513, Events=116

Factor Level Hazard Ratio P value
BMI overweight 1.85 (1.14, 2.99) 0.0128
BMI obese 1.9 (1.12, 3.22) 0.0174
BMI underweight 0 (0, Inf) 0.993
smoking previous 0.82 (0.53, 1.27) 0.367
smoking current 1.79 (1.09, 2.95) 0.0215
hypertension yes 1.55 (1.01, 2.37) 0.0432
