  1. Abbreviations: SBP, systolic blood pressure; DBP, diastolic blood pressure; 25(OH)D3, 25-hydroxyvitamin D3; iPTH, intact parathyroid hormone; BP medication, antihypertensive medication as dummy variable (no/yes); TBF, total body fat; WHR, waist-to-hip ratio. a) Multiple linear regression analyses with SBP or DBP as dependent variables. The results of the linear regression analyses are expressed in terms of B (the unstandardised coefficient), β (the standardised coefficient), and the adjusted coefficient of determination (corr. R2).
