____________________________________

The characters after the % change can be used to determine the statistical significance.

Example:      	

1.2%   = not statistically significant
2.3%*  = statistically significant  (denoted by the *)
2.3%#  = manual calculation of significance required due to change in scan mode  (denoted by the #).

In the last case, the following standards can be used to assess significance.

Lumbar spine: change of at least 0.022 gms/cm2

Total hip: change of at least 0.027 gms/cm2

Forearm R+U 1/3 change of at least 0.015 gms/cm2
