Just saw this in the editorial comment section of the journal Gastroenterology. What they say is that they are going to introduce the highlighting of the co-first authors in case such an article (Where few authors have made equal contribution) is cited in the references section.
[important]A note in such cases will follow the references section that states: “Author names in bold designate shared co-first authorship.” An example of such a cited reference is: Pox CP, Altenhofen L, Brenner H, et al. Efficacy of a nationwide screening colonoscopy program for colorectal cancer. Gastroenterology 2012;142: 1460–1467. [/important]
Haven’t seen anything like this in Chemistry/ Med Chem Journals ….yet!
