The authors wish to make a modification in their article as regards a study by Li et al. (2016) to exclude reporting of the short-term, interim effect of β-glucan on glycemic measures and only retain analysis for the long-term effects, to avoid study duplication. As a result of one comparison exclusion, corrections to the following tables and figures were made: Figures 1–3, Table 1, and relevant Supplementary Data. There are no significant changes in statistical outcomes, with a slight improvement in numerical values in favor of fiber that do not change results interpretation.
The authors confirm that these modifications do not affect the remaining analysis or the conclusion.
The online version of this article (https://doi.org/10.2337/dc18-1126) has been corrected to reflect these changes.
