Hi well informed members. I'm working on something at the moment, for which I need the above info. I'm looking for some refs for figures relating disease prevalence to medical research funded, for conditions causing varying levels of disability. Preferably for this country, but US would be interesting too. I have seen people comparing these figures for ME, with other chronic diseases, such as MS and AIDS. My filing and indexing needs a complete overhaul and I know many of you are much more organised/have this info at your fingertips! Is there any research on the numbers of patients, who are mild/moderate/severe etc; other than the 25% quoted for those who are house or bed-bound? I don't suppose that looking at mean SF function from PACE would help as that only selected fatigued patients! Is there anything from US reflecting levels of disability? Thank you for your help.
