I read the article "Discovery doubles genetic clues to Alzheimer's" from CNN. The article refers to numbers from two different medical reports about Alzheimer's disease. It talks about the amount of genetic markers that researchers previously knew about, which was five, and how it now has been doubled to 10. The reporter also talks about the number of research groups doing this work and the number of patients they have information from. The number of people who currently have Alzheimer's in America is talked about, as well as a predicted number for the future.
The writer presented the numbers in a clear, easily understandable way. She crunched the numbers to convey them in the simplest form. For example, she said something doubled. She attributed all of the numbers and information she used. One source was a survey from Nature Genetics, other sources were professors from universities working on the research, and the Alzheimer's Association.
