Informed consent for genetic research on blood stored for more than a decade: population based study

In redrafting the line drawing in this article by Birgitta Stegmayr and Kjell Asplund (21 September, pp 634-5), we inadvertently reversed the numbers given for the participants who wanted to be contacted before every new research project in which their blood sample was intended to be used and those who did not want to be contacted (bottom left in figure). The figure should have shown that 202 participants wanted to be contacted, and 1019 did not.
