Pulmonary function of patients with signs of pulmonary involvement (n=749)

Variables	Patients with signs of pulmonary involvement (n=749)
mMRC ≥2	229/742 (30.9)
Altered oximetry*	71/675 (10.5)
CXR (score 1)	200/629 (31.8)
FVC<LLN	212/642 (33)

Values are presented as n/N (%).

*Resting SpO₂ ≤90% or a decrease in SpO₂ of ≥4% during the 1 min sit and stand test.

CXR, chest X-ray; FVC, forced vital capacity; LLN, lower limit of normal; mMRC, modified Medical Research Council dyspnoea scale.
