Univariate analyses explore the associations between individual risk factors and OH. Multivariate models included all the listed risk factors in the same regression model. *P < 0.05; ^†P < 0.01; ^‡P < 0.001. Abbreviations: OR, odds ratio; CI, confidence interval; SBP, systolic blood pressure; DBP, diastolic blood pressure; PP, pulse pressure; BMI, body mass index.
