Can we trust free software? Or better: would you trust your health to  software that nobody paid for? Software that is open to use and adapt by whomever wants to? Well, the use of the free R-Project in clinical trials is considered more and more seriously. Recently,  The R Foundation for Statistical Computing unanimously adopted a document titled: <i><a href="http://www.r-project.org/doc/R-FDA.pdf">&#8220;R: Regulatory Compliance and Validation Issues. A Guidance Document for the Use of R in Regulated Clinical Trial Environments&#8221;</a></i><br />
<span id="more-624"></span><br />
From the announcement:</p>
<blockquote><p>
The document provides extensive background and detailed guidance for the<br />
use of R within the regulated framework of human clinical trials,<br />
covering GxP and 21 CFR Part 11 issues. This document should serve R<br />
users as a key reference for their internal regulatory activities<br />
relating to the use of statistical software for clinical trials.
</p></blockquote>
<p>One or two years ago, there was some discussion on the use of R-Project in clinical trials on the R Help mailing lists. General concerns were that employers, journals, or (in the United States) the FDA would not accept studies performed using R-Project. Perhaps this document will help in gaining more acceptance of this excellent piece of analytic software.</p>
<p>If you&#8217;re working in a clinical or medical setting, please let me know: do you or your colleagues use R-Project? Or, if not, what type of statistical software do you use?</p>
