erratum 20 January 2009
Soren Brage Send letter to journal: Re: erratum soren.brage{at}mrc-epid.cam.ac.uk Soren Brage	Table 3 The constant should be +207 (not -207 as published) in the last equation (eq.7). The correct equation is: PAI = 5.5 * HRaS + 1.6 * HRaS*gender - 7.8 * SHR*gender + 338 * gender - 4.7 * SHR + 207 We submitted an erratum to the editorial office (via email), shortly after publication of the article but we can not find links to this on your website. This eLetter may not be the appropriate route for errata but we just wanted to make sure our error was documented somewhere. We can only repeat what we said in our original email that we are very sorry that we did not spot the typo at the proof reading stage and further apologise that we did not more actively follow up the erratum. On behalf of all authors, Dr. Soren Brage
