First review round: 6.0 weeks. Overall rating: 0 (very bad).
Outcome: Rejected.
Motivation:
A statistical review was only introduced in the 4th review round. The editor agreed with the statistical reviewer's comments and rejected the manuscript around 9 months after our submission. I believe the 4th review round was too late to add a statistical review, and at the very last, the editor should have given us an opportunity to revise and respond to the reviewer's comments.
