## Post #1 by @pacharanero

At RCPCH we have been collecting information for at least 5 years about which growth reference data is available.

We have tabulated this list of available references, where we have it, in the GitHub repository linked below. There is a [table in the documentation](https://growth.rcpch.ac.uk/clinician/growth-references/#reference-library) which lists the references and where those are in use primarily.

https://github.com/rcpch/growth-references

What we **don't** yet have is the 'reverse' --- a list of **countries** and *which references they use*. For example, in the Republic of Ireland they use the UK-WHO references, something I only found out about this week, and was mildly surprised about since very often the HSE does its own version of things rather than using the UK version (for understandable Independence and historical/political reasons)

I wonder if the Growth Charts community here would be able to help us by clarifying exactly what type of references are in use for their country.

In particular we would need to know:
* The 'standard' child reference (and links to data if available)
* Which references are used for preterm infants (if different)
* Whether special references are available for some conditions (for example Down/Turner syndromes)
* Any other important caveats or local variances.

I will collate any responses in a table in this topic, for future reference.
