Two kinds of software tools for conversion between raw
FEV_{1} and percentiles of FEV_{1} among
patients with cystic fibrosis are available for download from
this page:

- A command-line Windows executable which calculates the percentile for a single patient;
- A collection of functions written in R, an open source statistical package. These functions can handle large datasets.

Both also handle CF height percentiles.

Neither height nor FEV_{1} equations have been implemented
in Excel or SAS as yet.

This is the program that works behind the web conversion tool.
It converts FEV_{1} and height into percentiles and vice
versa, for a single patient at a time.

This is a collection of functions written in R, which
convert FEV_{1} and height into percentiles and vice
versa for a whole data set. It requires an installation of R on
your computer (available for download
here). Datasets can be
exported from almost any other software in the comma separated
format, imported into R to calculate the percentiles and
exported again through the same format.
