TABLE 3.

Change in diffusion capacity measures per 1-sd increase in skin autofluorescence (SAF) (n=3889)

		Change in diffusing capacity per 1-sd increase in SAF (95% CI)	p-value
D_LCO mmol·min⁻¹·kPa⁻¹	Model 1	−0.16 (−0.20– −0.12)	<0.001
D_LCO mmol·min⁻¹·kPa⁻¹	Model 2	−0.07 (−0.11– −0.03)	<0.001
D_LCO/V_A mmol·min⁻¹·kPa⁻¹·L⁻¹	Model 1	−0.02 (−0.03– −0.02)	<0.001
D_LCO/V_A mmol·min⁻¹·kPa⁻¹·L⁻¹	Model 2	−0.01 (−0.02–0.00)	0.002

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). D_LCO: diffusing capacity of the lung for carbon monoxide; V_A: alveolar volume.
