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=153979, Events=141

Factor Level Hazard Ratio P value
BMI overweight 1.41 (0.92, 2.17) 0.113
BMI obese 1.52 (0.95, 2.43) 0.0832
BMI underweight 0 (0, Inf) 0.992
smoking previous 0.89 (0.63, 1.27) 0.531
smoking current 0.83 (0.44, 1.56) 0.561
hypertension yes 1.5 (1.06, 2.12) 0.0207
