Fig 1 Scatterplots show the relationships between (A) improvement in the dyspnea index at 6 months vs baseline residual volume (RV) and (B) postoperative change in forced expiratory volume in 1 second (FEV1) vs the postoperative change in residual volume (ΔRV). The solid lines are the linear regressions, while the dotted lines represent the 95% confidence interval. The Spearman correlation coefficient (r) and p values are shown.
