Factors associated with the difference between office BP and ABP: Multivariate analysis

VariablesDifference in BP (mmHg)P Value
Men (versus women)0.310.67
Age (10 yr)0.560.07
eGFR (10 ml/min per 1.73 m2)−0.560.05
Antihypertensive medicine use2.610.03
Much difficulty in sleep0.860.31
Winter (versus summer)−0.520.50
  • Multiple regression analysis was performed for multivariate evaluations including sex, other variables with P value <10% explored in Table 3, and patients’ questionnaire variables as independent variables. As for renal function, we adopted eGFR instead of CKD stages. We did not incorporate proteinuria into this model. ABP, ambulatory BP; BMI, body mass index; eGFR, estimated GFR.
