  1. Abbreviations: CI, confidence interval; DBP, diastolic blood pressure; LVH, left ventricular hypertrophy; OR, odds ratio; SBP, systolic blood pressure.
  2. If models included evening home BP, data were further adjusted for BP measurements before or after bathing and before or after consuming alcohol. The variance inflations were 1.14–2.26. Therefore the possibilities of multicollinearity in this analysis was slight.
  3. aModels were adjusted for body mass index and office heart rate.
  4. bModels were adjusted for age and timing of taking medication in the evening.
