DEPRECATED PROJECT

This repository is now deprecated and archived as there is a much better alternative available in the form of the RCPCH Digital Growth Charts API, which can be found at https://growth.rcpch.ac.uk/ or within the RCPCH's GitHub organisation https://github.com/rcpch

A suite of tools for calculating paediatric growth centiles from LMS statistical tables, including a basic scriptology, REST API, UI elements, supporting documentation

• Centile-js directory contains UK90.js - basic code in javascript which will return a centile, when given age, sex, height, weight as input. As it is currently written there is no command line usage, it would need to be integrated into a webapp or node.js for use. It is left here as a resource of working statistical code for conversion of LMS tables into centiles.

• EWD-based-webapp contains the code and all dependencies for the EWD-based web application

• Mobile-webapp is essentially a fork of the centile_app project with the aim of allowing the calculations to be done in the client device. It's aimed at mobile workers such as hospital doctors.

• PyCentile contains Python scripts for calculating centiles from LMS data + age, sex, height, weight information. There are two different versions, one for use with the UK90 LMS tables and the other for use with the CDC's USA LMS tables.
