mBODE and survival post-LVRS

Kaplan-Meier survival curves (starting at 6 months after randomization [F06]) for the surgically treated patients in the National Emphysema Treatment Trial who survived and were able to provide data to calculate mBODE (modified Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity) 6 (F06) months after randomization. Survival curves are segregated by groups who experienced a decrease in mBODE > 1 (blue), a rise in mBODE > 1 (red), no change in mBODE (-1 to 1 point change) (green), or missing data (black) from baseline to the starting time point.
