One of the Reviewer comments for a paper that I sent to a journal is the following:
The authors claim that they are the first to use subjective questionnaires to develop predictive models. This is not accurate, there are many studies on the literature that use questionnaires and some of them even compare PQ to objective data coming from sensors in order to find correlations.
Now the problem is that I have done a thorough check and have observed that this paper indeed is first to use questionnaire to develop predicitve models for the particular disorder. Now how do I handle such a comment?
