Abbreviations: OR: Odds ratio; CI: Confidence interval.

Model 1 includes adjustment for age, sex.

Model 2 includes variables in Model 1 and current smoking and drinking status, marital status, education years and body mass index.

Model 3 includes variables in Models 1 and 2 and frail status.

Linear p-trend represents the p-value for a linear trend across the diastolic blood pressure categories. Quadratic p-trend represents the p-value for a deviation from linearity across the diastolic blood pressure categories.
