Values are given as mean ± SD or n (%) for all randomized subjects. For comparisons between groups, Fisher´s exact test was used for dichotomous variables, t-test was used for normally distributed continuous parameters and Mann-Whitney U test was used for non-normally distributed parameters. BMI = body mass index, NS = non-significant.
