Figure 3.
Change in body mass index (BMI) at 6 months and percent changes in lung function measures from baseline to 6 months (except the diffusing capacity of carbon monoxide [DlCO], which was assessed at 12 mo). Shaded columns represent patients who had an increase in BMI of at least 5% at 6 months, and open columns represent patients with a change in BMI less than 5%. Data represent the lung volume reduction surgery (LVRS) treatment group and are expressed as means ± SE. *P < 0.0001 for ΔBMI ≥ 5% versus ΔBMI < 5%.
