Re: Osteopenia scores; anyone know what this means?

[Guest guest]

this is all statistical anaylsis information.

SD = standard deviation

Mean = average

So this means that the average incidence of spine fracture per 1000

person years for a 64 year old is 9.

If you think about a picture of a bell then 9 is in the middle. if

you go a little to the left on the left hand sides down slope you

come to 5, if you go farther down the left side you come to the 4.

now you go to the right of the center and go down and come to 18.

they should tell you what the standard deviation is so that you know

how far apart these numbers are from eachother. i am not sure if

this is making sense or not. i do appologize if this is more

confusing then helpful.

i will have my husband write a better explaination later. he

probably wont have time till tonight. he is better at explaining

things in non mathematical terminology.
