The INTERGROWTH-21st Consortium has developed an easy-to-use tool that enables fetal, pre-term and newborn measurements to be compared against newly created standards

These applications allow data to be entered manually so that the size of individuals can be compared to, and plotted graphically against, the international standards and references (as shown below). 

In addition, large datasets can be imported directly into the application, which then calculates the respective centiles and z-scores based on the INTERGROWTH-21st standards and references.  The results can be exported for further analysis.

An updated, online, browser only version is available via the links on the right.
