Linear regression analysis – resting heart rate in relation to spirometry lung function parameters

	Basic model			Adjustment model 1			Adjustment model 2
	β	R2	p-value	β	R2	p-value	β	R2	p-value
FVC	-6.39	0.71	<0.001	-6.45	0.71	<0.001	-6.07	0.70	<0.001
FEV1	-6.16	0.66	<0.001	-6.12	0.66	<0.001	-6.04	0.66	<0.001
DLCO	-0.010	0.55	<0.001	-0.010	0.58	<0.001	-0.015	0.58	<0.001

β = The increase in FVC/FEV₁/D_LCO for every 1 bpm increase in resting heart rate

FVC (ml); FEV₁ (ml); D_LCO (mmol/(min*kPa))

Basic model (adjusted for age, sex and height)

Adjustment model 1 (age, sex, height, current smoking)

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)
