aThe differences between the two groups for the study outcomes were evaluated with ANOVA or with the Mann–Whitney non-parametric test, depending on the distribution of the data, for continuous variables and with the chi-square test or with the exact test of Fisher, if appropriate, for categorical variables. All the analyses were conducted according to the intention to treat principle. The T-test was used for hypothesis testing. Differences with p < 0.05 will be considered significant
