3. Fig 2
Box plot of the MEF50/MIF50 ratio over time. Blue boxes represent patients without pulmonary disease (n=55), while green boxes represent patients with COPD (n=20). For both groups, MEF50/MIF50 ratio increased significantly after surgery and returned to baseline within 24 h. Because of their obstructive pulmonary disease, MEF50/MIF50 ratio was significantly lower for COPD patients.

Box plot of the FEV1 of patients without pulmonary disease (blue boxes; n=55) and patients with COPD (green boxes; n=20) over time. For both groups, FEV1 was significantly reduced after operation and returned to baseline (patients without COPD) or close to baseline (patients with COPD) up to the 5 days.
