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=152960, Events=163

Factor Level Hazard Ratio P value
BMI overweight 1.3 (0.88, 1.92) 0.185
BMI obese 1.75 (1.16, 2.63) 0.00738
BMI underweight 0 (0, Inf) 0.991
smoking previous 1.02 (0.7, 1.49) 0.904
smoking current 3.45 (2.37, 5.02) 8.66e-11
hypertension yes 1.36 (0.94, 1.95) 0.101
