Usage:
get_who_growth_reference(%args) -> [status, msg, payload, meta]
Lookup height/weight in the WHO growth chart (a.k.a. growth reference, growth standards).
Caveats:
Currently the z-zcore line values (e.g. height_Z1, height_Z-1, etc) are calculated using linear interpolation.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
age => duration
dob => date
gender* => str
height => float
Specify height to calculate percentile.
now => date
Assume now is this date, instead of current date.
weight => float
Specify weight to calculate percentile.
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
Return value: (any)
