Spiegelhalter DJ. Understanding uncertainty. [Ann Fam Med. 6(3):196–197](http://www.annfammed.org/lookup/volpage/6/196).

In the print version of the May/June 2008 *Annals of Family Medicine*, the editorial by Speigelhalter refers to an article entitled “Patients Prefer Pictures to Numbers to Express Cardiovascular Benefit From Treatment” as authored by Chan et al. The correct attribution is Goodyear-Smith et al. The print version therefore departs from the online version.
