T value is more significant I guess :
Z values compares you to other people who are the same age as you are so the Z score may not be as valuable because you are comparing yourself to a skewed population,
whereas
the fracture risk is based on T score or value, for ex. if you are 80 and you have a normal Z score you could potentially have a T score of minus 2½ and be at a 2% to 4% increase risk for fracture.
