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
