 The paper aims to use nanopublications as a scientific publishing approach to establish a citation network of claims about the annual rate of physician suicide among U.S. physicians, but the results show that the network is not fully connected, no single primary source could be identified, and all endpoint citations had a claim with no further citation or could not be accessed to verify the claim. The nanopublications strategy also enabled the capture of variant claims published on a website. This article was authored by Tiffany I. Leong, Tobias Kuhn, and Michel Demontier.
