why did DEXA chose for the footer in the bottom?

It seems there's a misunderstanding. The term "DEXA" in this context generally refers to a type of scan used to measure body composition, including bone mineral density and body fat. The question about "choosing for the footer in the bottom" doesn't align with the known uses of DEXA. If you were referring to a different context or need a specific detail about DEXA scans, please provide more information, and I can help clarify further.

For information on DEXA scans, they are highly valued for their precision in measuring body composition parameters such as bone mineral density, body fat, and lean mass. This makes them an invaluable tool in various medical and fitness settings 1 2.
