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=153646, Events=402

Factor Level Hazard Ratio P value
BMI overweight 1.07 (0.82, 1.39) 0.637
BMI obese 2.13 (1.65, 2.77) 1.06e-08
BMI underweight 0 (0, Inf) 0.986
