  1. A negative β represents a negative correlation between the lung function parameter and orthostatic DBP reaction (e.g. decreasing FVC with decreasing orthostatic DBP)
  2. β = The increase in FVC/FEV1/DLCO for every 1 mmHg decrease in orthostatic DBP reaction
  3. FVC (ml); FEV1 (ml); DLCO (mmol/(min*kPa))
  4. Basic model (adjusted for age, sex and height)
  5. Adjustment model 1 (age, sex, height, current smoking)
  6. Adjustment model 2 (age, sex, height, current smoking, supine SBP, carotid artery plaques, coronary calcium score, antihypertensive drugs, β-blockers, diabetes, inhalation medication for COPD or asthma)
