Fig. 1

The relationship between PFT, CT, CPET parameters and CI. Adjusted OR (with upper and lower 95% CIs) for likelihood of having lung function, imaging and/or cardiopulmonary exercise response impairment in participants with CI compared with those without CI. Abbreviations PFT = pulmonary function test; CT = computed tomography; CPET = cardiopulmonary exercise test; CI = chronotropic incompetence; OR = odds ratio; CI = confidence interval; IC = inspiratory capacity; VV = vascular volume; VE/VCO2 = ventilatory equivalent for carbon dioxide
