Calculates the z-score, percentile, and normal limits for a measured pulse wave velocity (PWV) based on the patient's age and gender. Provides LMS parameters to calculate z-scores for pulse wave velocity (PWV) relative to age in children and young adults.

The underlying data and methodology are from: Voges I, Jerosch-Herold M, Hedderich J, et al. Normal values of aortic dimensions, distensibility, and pulse wave velocity in children and young adults: a cross-sectional study. J Cardiovasc Magn Reson. 2012;14:77.

Measurement Context: Pulse wave velocity is calculated by phase contrast CMR for the distance between the sinotubular junction and the proximal descending aorta. Transit time is calculated from the midpoint of the systolic up-slope on the flow versus time curve.

LMS Parameters:

• L (Lambda): Skewness of the distribution.
• M (Mu): Median value.
• S (Sigma): Coefficient of variation.

Important Notes:

• HTTP Status Code: All responses have an HTTP 200 OK status. You must check the JSON body for an error field to determine if the request was successful.
• Age: The age parameter should be the patient's age in whole years. For infants under 1 year old, use age=0.
