      The Z-score: The “age-matched” or Z-score compares your BMD to what might be expected in someone your age and body size. Again, the Z-score is in units of standard deviations and shows whether your bones are more dense (+), or less dense ( -) than what might be expected. At young ages, the T-score and Z-score values will be similar.

      A z score of 0 means 50% of scores fall below the mean score. So we still need to find another 33% of the area under the standard normal curve (50% + 33% = 83%). In this case, we can work backwards or 100% - 83% (or 17%) to find the area beyond that point. The z score is .95 (area of 17.11% beyond).

A z-score of 0 is simply the median at that sex/age, and in this case, the BMI is 20.76 kg/m 2. (When z=0, L × S × z is 0, and the BMI is equal to M in equation #2).
