This is a splendid tour de force paper but:
1. It is about writing abstracts rather than articles.
2. It is known that abstracts are more difficult to read than articles (Hartley, J. Pennebaker, J. Fox, C. Abstracts, introductions and discussions. How far do they differ in style? Scientometrics. 2003:57(3):389-398
3. Abstracts are judged to be clearer when they are written in the structured form - an issue not considered here (Hartley, J. Current findings from research on structured abstracts: An update. Journal of the Medical Library Association. 2014:102(3):146-148
