| COPD | All Controls | |
|---|---|---|
| Plasma glucose level, mmol/L | 6.2 ± 1.6 | 5.9 ± 0.9 1 |
| Systolic blood pressure, mmHg | 145 ± 22 | 143 ± 20 |
| Diastolic blood pressure, mmHg | 84 ± 9 | 84 ± 10 |
| Pulse wave velocity, m/s | 10.6 ± 2.7 | 8.8 ± 2.2 1 |
| Plasma triglyceride level, mmol/L | 1.5 ± 0.8 | 1.4 ± 1.0 |
| Plasma HDL level, mmol/L | 1.6 ± 0.5 | 1.6 ± 0.5 |
| cIMT, µm | 836 ± 181 | 800 ± 156 1 |
| HOMA index | 3.4 ± 6.0 | 2.0 ± 1.4 1 |

| BMI, kg/m2 | 26.9 ± 5.4 | 26.9 ± 3.4 |
| FFMI, kg/m2 | 17.6 ± 2.6 | 18.1 ± 3.1 |
| Lowest T score | −1.7 ± 1.0 | −0.9 ± 1.1 1 |

Abbreviations: HDL = high density lipoprotein; cIMT= carotid intima media thickness; HOMA = homeostasis model assessment method; GFR = glomerular filtration rate; BMI = body mass index; FFMI = fat-free mass index; HADS = Hospital Anxiety and Depression Scale. Summary variables are presented as mean ± standard deviation for quantitative variables, and percentage for discrete variables. 1 p < 0.05 versus COPD group. Missing data for subjects with COPD: 26 subjects with COPD lacked an acceptable quality pulse wave velocity measurement; 15 subjects lacked an acceptable quality carotid intima-media thickness measurement, 11 did not fill out the entire hospital anxiety and depression scale, 1 subject did not give a blood sample, for 6 additional patients insulin levels could not be measured, and 4 subjects did not have a dual-energy X-ray absorptiometry. Missing data for controls: 9 control subjects lacked an acceptable quality pulse wave velocity measurement; 8 subjects lacked an acceptable quality carotid intima-media thickness measurement; insulin level could not be measured for one subject; 1 did not fill out the entire hospital anxiety and depression scale.
