Elementary statistics says c). 
In 10000 people, less than 1 has the disease, but the test will produce approx. 100 false positives. Hence, the probability that a random positive actually has the disease is smaller than 1/100=1%.BTW, welcome back Buzz!

So of the up to 14% of BFS'ers that developed MND (average over 45 years of age), how many false positives could there have been?

Great to know. Thank you for clearing it up. Funny how I get called out on the "wrong" information and get "silence" on the good information. Just saying.

MJP, FWIW I am grateful for your contributions and I am glad you found a possible explanation of your symptoms.
