In the published version of this article, there was an error in reporting the final number of the patients who finished the study. In this study, data for 45 patients in the intervention and 43 patients in the placebo group were analyzed and reported based on appropriate statistical tests (t-test or ANCOVA). At baseline, 99 patients were randomized to two groups to receive either synbiotic (n=50) or placebo (n=49). Five patients in the intervention and 6 in the placebo group did not finish the study. This correction should be considered in the Abstract, main text, and CONSORT flow chart.
In Table 1, the range values reported for BMI are in fact “Inter-quartile range” values.
In Table 2, the correct difference and 95% CI values for post- and change values of fibre intake are as below:
Post- fibre: Difference: −0.326; 95% CI: −0.93 to 0.28
Change- fibre: Difference: −0.003; 95% CI: −0.38 to 0.37
