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=153520, Events=195

Factor Level Hazard Ratio P value
BMI overweight 1.39 (0.98, 1.99) 0.068
BMI obese 1.63 (1.11, 2.4) 0.0126
BMI underweight 0 (0, Inf) 0.99
smoking previous 1.5 (1.1, 2.03) 0.00988
