Back in the 60s I was doing some research in leukaemia and its incidence in clusters. I learnt then that rare disorders statistically cluster in groups of three without related causal effects. Can any statistician confirm or refute this?
GBS and CIDP are different diseases, yes campylobacter is one of the more common triggers for GBS but there really are no known triggers for CIDP. DocDavid
