Just a moment...
Interesting article, well known that hearing loss accelerates dementia. .
However, for us data geeks, our read of the article is that the study linked the Framingham Heart Study data with the hearing/dementia data for a very large dataset, and pretty good statistical results. . p-values at 0.02,
The FHS dataset has alot of very good long term data, not just heart data, and yes, there will be a bunch of data mining, but that is what lots of good data is there for, to look for linkages which are currently unknown or undiscovered.
good luck to us!
