Paper status changed from under review to Awaiting Decision
It depends. If you know that in this journal (and you discipline) the papers are typically reviewed fast (e.g., one month), then it indeed likely that your paper is already after peer-review. In contrast, if in this journal the peer-review typically takes several months, then it might be long desk-rejection. It is indeed not rare to get desk rejection after several weeks. Also, keep in mind rejection rate without review in your journal. If it is low, then it more likely to be already after review.
