Fig. 1 The number of patients undergoing transthoracic resection (open bars) and transhiatal resection (filled bars) of esophageal cancer grouped by 2-year intervals. The numbers above the columns indicate the percentages of patients undergoing transhiatal resection during each interval.

Fig. 2 The number of patients without (open bars) and with (filled bars) pulmonary complications after esophagectomy for cancer grouped by 2-year intervals. The numbers above the columns are the percentages of patients who had postoperative pulmonary complications during each interval.

Fig. 4 The incidence of pulmonary (P =.013), cardiovascular (P =.005), and cardiopulmonary (P =.001) complications in relation to the predictive score.

Fig. 5 Receiver operating characteristic curves for the scoring system relative to pulmonary complications (circles, r2 = 0.99), cardiovascular (triangles, r2 = 0.99), and cardiopulmonary complications (inverted triangles, r2 = 0.99). The line of unity (no discrimination) is depicted as a dashed line.
