In this paper by Calman A MacLennan and colleagues, we gave the wrong unit for the CD4 cell count (BMJ 2007;335:190-4, 28 Jul, doi: 10.1136/bmj.39268.719780.BE). Throughout the article we gave the unit as ×109/l, whereas the correct unit is cells/µl (cells per microlitre). This error has been corrected in the online pdf and html versions of the article.
