I have recently received my first manuscript back for major revisions and found one of the reviewers comments strange. Within the comments the reviewer refers to the paper as "Author D et al's paper". As first Author (Author A), I am a bit confronted by this and concerned that there is a general perception that the corresponding and most senior author has done most of the work, as he is more recognised within the field. This is aside from the fact that out of the 4 authors on the paper, I am the only one to have written and researched the literature review, with edits from Author D. My question therefore is: Is this common? Is there any reason for concern of being undermined?
I'd appreciate some insight why reviewers would do this.
