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=153561, Events=310

Factor Level Hazard Ratio P value
BMI overweight 0.89 (0.68, 1.17) 0.406
BMI obese 1.13 (0.84, 1.51) 0.416
BMI underweight 0 (0, Inf) 0.987
smoking previous 0.95 (0.75, 1.22) 0.699
smoking current 1.05 (0.72, 1.55) 0.789
hypertension yes 1.12 (0.87, 1.45) 0.386
