Long-term lung function. a FEV1, b, FVC, c RV, and d TLC for the 29 W group (open bar), 32 W group (diagonal line bar) and 32 W confirmation group (32 W-CFM, gray bar) collected at baseline, 1, 2, and 3 years after TLD. Data presented are means ± SD. Combined values, “All”, are depicted as the red line. P < 0.05 for combined values compared with baseline is denoted by *. FEV1 forced expiratory volume in 1 s, FVC forced vital capacity, RV residual volume, TLC total lung capacity, TLD targeted lung denervation
