I've seen some journals now require (or at least suggest) including a graphical abstract for publication. In particular, Elsevier/Cell seems to advocate strongly for graphical abstracts as they can draw attention and attract readers.
There seems to be anecdotal evidence that this is the case. But, is there any study that supports this assumption? Does a graphical abstract lead to more readers, more citations, more media exposure, or improvement in any other metric of "impact"?
The only study I've found that tackles this question actually finds no evidence of this being the case when analysing papers published between 2014-2015 in the journal Molecules.
