Change in spirometry measures per 1-sd increase in skin autofluorescence (SAF) (n=4111)

		Per 1-sd increase in SAF (95% CI)	p-value
FEV₁ L	Model 1	−0.06 (−0.07– −0.04)	<0.001
FEV₁ L	Model 2	−0.03 (−0.04– −0.02)	<0.001
FVC L	Model 1	−0.05 (−0.07– −0.03)	<0.001
FVC L	Model 2	−0.03 (−0.05– −0.02)	<0.001
FEV₁/FVC	Model 1	−0.005 (−0.007– −0.003)	<0.001
FEV₁/FVC	Model 2	−0.002 (−0.004– −0.000)	0.120

Model 1 adjusted for age, height and sex. Model 2 adjusted for age, height, sex, weight, smoking status (never-, ex- and current smokers), pack-years, estimated glomerular filtration rate, diabetes, log(glycated haemoglobin), log(plasma glucose) and log(C-reactive protein). FEV₁: forced expiratory volume in 1 s; FVC: forced vital capacity.
