How to respond to reviewers that ask you to "look again at your results" without providing further details? Recently my research paper got major revision in which one of the reviewer ask me to look again at the results I have derived without pointing to any specific item of results. I have double checked my results and all results found to be correct and now I am confused that what actually reviewer is trying to say as he/she did not specifically mentioned nature of error in my results.

So how should I respond? (The second reviewer is satisfied with my results)
Email the editor to ask for clarification. They are the person you need to satisfy. If they don't understand what is needed either, they will either get in touch with the reviewer to ask, or they will tell you not to worry.
