The authors of a 2015 mouse study that linked certain emulsifiers to changes in the gut microbiome, immune cells, and body weight this month (May 4) added a corrigendum to clarify the ages of mice used in their experiments, and to share additional data on the animals’ weight change over time, Retraction Watch reported.

Study coauthor Andrew Gewirtz of Georgia State University told Retraction Watch that Nature requested the additional information after a “researcher inspecting it [the study] noticed a couple of area [sic] of imprecision.” In their notice, the researchers wrote that these clarifications “do not alter any of the central conclusions” of the paper, and are being “provided in the interests of transparency and reproducibility.”
