Text: A comparison of the medical and surgical arms of the combined CLVR study/OBEST population showed that LVRS was associated with a higher FEV (1) (167 mL or 24 % predicted ; 95 % confidence interval [CI], 29 to 304 ; p = 0. 017), lower residual volume (-1, 342 mL or 24. 5 % predicted ; 95 % CI, -1, 844 to -840 ; p < 0. 001), lower TLC (-1, 044 mL or 13 % predicted ; 95 % CI, -1483 to -605 ; p < 0. 001), and higher 6-min walk distance (148. 8 feet ; 95 % CI, 24. 3 to 273. 2 ; p = 0. 019).
