Time course of lung volume changes after SABR for upper tertile of V60BED3. a Treated lobe volume reduction (as % of total lung volume [TLV]) versus time (continuous) measured on serial diagnostic CT studies (black dots) and connected by a line for each patient (n = 21). The significant repeated-measure regression correlation indicates faster rate of volume change for upper (gray) versus lower (black) treated lobe location up to 10.1 months. b Treated lobe volume reduction measured on last CT follow-up indicating no significant difference in final volume reduction between upper and lower treated lobes. c Normalized (as fraction of maximum) treated lobe volume reduction (black dots) for each patient (n = 21) versus time (categorical) binned by 3-month intervals. Error bars demonstrate mean and 95 % confidence interval of the mean
