Each study in the Lancet have a lot of authors. I have read a number of them. Each study has the authors in several countries. The most authors were minister or co-minister. One author write the article in severe condition that can publish it in a journal with lowest impact, but they (minister and co-minister) received the data of each country and send to a co-author and published in a journal with high impact factor. Now which is better? A article with low impact and low author that all authors have worked on it or a article with more than 200 authors and high impact that just some authors have written it.
