Numbers for CIDP

I came across an article on the prevalence of CIDP in New South Wales, Australia [Ann. Neurol. 1999 Dec;46(6):910-3; PubMed summary: [URL=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=10589544&dopt=Citation]). The main conclusion is that the incidence rate was about 0.15 per 100000 and the prevalence was 2.0 per 100000. There could still be geographic effects, like in MS, and ethnic/racial effects, like in diabetes, but the numbers are probably fairly reasonable world-wide. If so, then there are about 120,000 people world-wide with CIDP at any given time.
