Biobank knowledge and research participation by group. Refusers, nonresponders and participants were asked whether they had heard of the Mayo Clinic Biobank before receiving the recruitment packet in the mail. They were also presented with a list of resources, such as the Biobank staff and family member, and asked whether they had consulted any of these resources or any other resource in making their participation decision. Individuals who consulted any resource are included as having looked for information in the second set of columns. Individuals were asked to report how much of the consent form they read in 5 categories ranging from ‘all of it’ to ‘none of it.’ The final set of columns displays those who reported that they read all or most of the document. p-Values were calculated using Fisher’s exact test.
