Means and standard errors of blood pressure measured on each of the two examination days were estimated by marginal means and corresponding standard errors from mixed-effects regression models.

p-Values were calculated using mixed-effects regression models.

Hypertension was defined as systolic blood pressure >140 mmHg or diastolic blood pressure >90 mmHg.
