1 Minimal alteration of pulmonary function after lobectomy in lung cancer patients with chronic obstructive pulmonary disease  Yasuo Sekine, MD, Takekazu Iwata, MD, Masako Chiyo, MD, Kazuhiro Yasufuku, MD, Shinichiro Motohashi, MD, Shigetoshi Yoshida, MD, Makoto Suzuki, MD, Toshihiko Iizasa, MD, Yukio Saitoh, MD, Takehiko Fujisawa, MD  The Annals of Thoracic Surgery  Volume 76, Issue 2, Pages (August 2003) DOI: /S (03)

2 Fig 1 The ratio of actual postoperative forced expiratory volume in 1 second to predicted postoperative forced expiratory volume in 1 second (apo/ppo FEV1) was higher in the chronic obstructive pulmonary disease (COPD) group than that in the non-COPD group (p < 0.01). (Dotted line = apo/ppoFEV1 = 1.0.) The Annals of Thoracic Surgery  , DOI: ( /S (03) )

3 Fig 2 The correlation between actual postoperative forced expiratory volume in 1 second (apoFEV1) and modified predicted postoperative forced expiratory volume in 1 second calculated by the new equation. Modified predicted postoperative forced expiratory volume in 1 second (ppoFEV1) was significantly correlated with apoFEV1 (R2 = 0.619, p < 0.001). (Black diamonds = the value of the modified ppoFEV1 plotted against the apoFEV1 values.) The Annals of Thoracic Surgery  , DOI: ( /S (03) )
