Table 1.
Characteristics of the whole population and univariable analysis.
The overall comparison among the three groups is shown.
Table 2.
Univariable analysis: Matched-paired comparison between groups.
Data are expressed as ORs, 95%CI and Pearson’s index. Continuous variables have been dichotomized. Only comparisons with statistical significance are reported.
