How do I calculate Echo Z-Scores?

There are currently two options for calculating the Z-scores for common echo measurements using the PHN models: (1) with an online Z-score calculator; or (2) with a table listing the exponential power to be used with body surface area (BSA), the mean value of the indexed measurement, and the standard deviation (SD) of the indexed measurement.
