Oops I think I m seeing the issue and it is indeed my error Somehow I missed that the epidemiology section had a second section regarding comorbidity in it I have struck my comment above and in the future I won t mention it again unless it s relevant to acknolwedge my previous error My apologies I would argue however that incidence which relates to new appearances of DID in the community at large isn t a good subheading because the section includes a discussion of both incidence and prevalence I suggest using a subheading with both Incidence and prevalence though another option is simply leaving it as epidemiology The WP MEDMOS Diseases or disorders or syndromes doesn t give much guiance here bar noting that Epidemiology should include incidence and prevalence information no mention of subsections Usually you leave it as a single larger section until it gets sufficiently lengthy that it makes sense to split them out which is itself dependent on the sources I ve replaced the section heading but both I and P The section overall needs fleshing out with more sources which I think are unfortunately lacking Searching on pubmed for DID and both incidence and prevalence turns up no articles specifically focussed on either topic t c Wikipedia s rules simple complex Again my apologies for the error the fault was completely mine
