Dihexa mastery course
Unit 5 of 10
The research-integrity problem
A dihexa course that skips the integrity actions is not honest.
The retraction and the expression of concern
A dihexa course that skips the integrity actions is not honest. The journal issued four notices of concern in September 2021, two of which land on foundational dihexa papers: the 2014 mechanism paper, which was then retracted in 2025, and the 2013 dose-response paper, which still carries its notice.
This unit explains what those notices mean, which papers are affected, and how the flagged findings quietly power the confident claims you meet in the wild. It is the heart of the honest case.
