So, you have your Z-Score. Now what?
Certainly, you can use it to dichotomize your findings into normal or abnormal. Possibly, you might use the z-score to further stratify your abnormal findings into mild, moderate, or severe (dilatation or hypoplasia)- which leads me to a couple of central questions, which may challenge some accepted practices:
- what z-scores do you consider normal?
- what z-scores do you consider as the thresholds for varying grades of abnormal?
