RESULTS
Sixty-seven patients were enrolled in group 1 and group 2, respectively. Baseline data concerning age, gender and number of comorbidities in both groups are shown in Table 1 .
Patients of the two groups didn’t show difference in average value of age and sex (Table 1). Moreover, the analysis of the number of comorbidities present in each individual of each groups did not show statistical differences (p> 0.05 for each class analyzed).
