Question Description:
After several rounds of revision, when the revised manuscript was submitted, the status showed 'quality check started' - 'peer review' - 'decision started.' What do these status changes mean?
Answer
It is clear from the status descriptions that your revised manuscript was sent for peer review again. This procedure is followed by most journals. The status 'Decision started' indicates that the peer review process for your manuscript is complete and the paper is now with the editor. The editor is probably going through the reviews to arrive at a decision. Hopefully, you will be informed of the decision soon.
