	Patients postponed for medical reasonsn = 39	Rest of the patientsn = 503	Statistical Significance
Age	69.4	59.8	p < 0.01
Gender (male)	32 (82%)	352 (69.9%)	p < 0.01
Years of education	7.6	7.5	non significant
Scheduled for major/oncologic surgery (lobectomy, bilobectomy, pulmonectomy)	29 (74.3%)	229 (45.5)	p < 0.001
Scheduled for minor/surgery for benign disease (biopsies, bullectomy/pleurodesis)	10 (25.64%)	271 (53.87%)	p < 0.01

The table shows comparative analysis of certain parameters between the group of patients whose operation was postponed for medical reasons and the rest of the patients. The x 2 criterion was applied for categorical parameters, the t-student (unpaired) for continuous ones. The Kolmogorov-Smirnoff test was used for the evaluation of normal distribution of samples. The level of statistical significance was set at a level for p < 0.05
