To the Editor:

Professor Czerwinski corrects our misstatement that FRAX is available in Poland as a CD when it is in fact available as a handheld calculator. We laud the continued increase in availability of FRAX, now in 18 languages including Polish. FRAX is available on the Web, as a desktop application, as an iPhone application, and now as a hand-held calculator. We will follow with interest the validation of the calculator against online FRAX and possible use in countries with poor or no Internet access.

Thank you,
