Change Details: The original online version of this article was revised. In the original version of the manuscript, we reported the results of the primary study outcome providing data on per-protocol analysis (PPA) and intention-to-treat analysis (ITT), assuming a best-case scenario (i.e., with MD children lost to follow-up (n = 5) assigned a positive outcome and with CT children lost to follow-up (n = 2) assigned a negative outcome), and a worst-case scenario (i.e., with MD children lost to follow-up (n = 5) assigned a negative outcome and with CT children lost to follow-up (n = 2) assigned a positive outcome). Subsequently, due to the length of the manuscript, Table 2 was revised with the aim of presenting only the worst-case scenario data of the ITT analysis. Unfortunately, due to a cut-and-paste error, in the manuscript as well as in Table 2 we stated that data were referring to worst-case scenario, whereas the data provided in the text referred to best-case scenario. Please be assured that this error does not affect the overall findings of the study. As confirmed by the PPA reporting that the absolute risk difference in overweight or obesity was -24% (95% CI -38% to -9%) for the MD arm in comparison to the CT arm, resulting in an NNT of 4 (95% CI 2 to 12), we feel that our conclusions remain valid: Mediterranean Diet has proven to be an effective strategy in preventing obesity in the offspring of women who completed the follow-up.
