Fig 1 Inclusion schema and resultant pairs after propensity score matching. (FEV1 = forced expiratory volume in 1 second; LS = laboratory spirometry; OS = office spirometry; PFT = pulmonary function test; Preop = preoperative.)

Fig 2 Distribution of propensity score (A) before and (B) after matching office spirometry and laboratory spirometry patients. Purple represents the propensity scores for office spirometry while orange represents the propensity scores of laboratory spirometry. The region of overlapping propensity scores is therefore displayed as pink.

Fig 3 Standardized differences before and after propensity score matching for variables included in the propensity score logistic regression model. Blue dashed vertical lines represent the limits, ±10%, outside of which standardized differences indicate imbalance. (ASA = American Society of Anesthesiologists; FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity.)
