Title: what's the odds??
Post by dougW on Aug 23^rd, 2007, 12:18am

From the latest issue of Cephalalgia )abstract only)

Prevalence of cluster headache in a population-based sample in Germany

Department of Neurology, University Hospital Essen, Essen, Germany

A population-based sample of 6000 inhabitants of the city of Essen in Germany was screened using a standard questionnaire for possible cluster headache (CH). Fifty-six percent responded (N = 3336, 50.5% of them women, mean age 44.7 ± 12.7 years). All suspected cases (N = 182) were interviewed by a neurologist. Four subjects with CH (three men) were identified. The 1-year prevalence of CH was estimated to be 119/100 000 (95% confidence interval 3, 238/100 000).

Hmmm. 6000 surveys, 3336 respondents. Can we assume the other 49.5% don't have headaches at all?
And off the suspected cases (182) only 4 confirmed cases of CH.
The numbers seem "suspect". ;-)

It doesn't sound that far off does it ? That's less than 1 in 1,000 people with 3 out of 4 being male. Although, there's no way to be totally sure, I would think that those who didn't respond, weren't interested in the survey and probably had no problems with headaches.

It does kind of sound like 'useless information' though.
