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=147230, Events=709

Factor Level Hazard Ratio P value
BMI overweight 1.31 (1.08, 1.58) 0.00511
BMI obese 1.42 (1.15, 1.75) 0.0011
BMI underweight 0 (0, Inf) 0.982
smoking previous 1.11 (0.94, 1.32) 0.217
smoking current 2.52 (2.07, 3.07) 3.95e-20
