Willingness to participate in biobank research. In 12 of 22 pairwise comparisons, factual willingness to participate in biobank research was higher than estimated in the corresponding surveys. Six comparisons yielded the opposite result. In two of these (IE and US2), the biobank studies recruited participants by asking them to supply buccal swabs by mail. In three others (GB4, GB5, and GB6) the first stage of recruitment to the biobank study in question (UK Biobank) relied on potential subjects to respond to a mailed invitation, which could explain part of the dropout. Significant differences (P<0.05) are marked by an asterisk. Each comparison has an index that identifies the study country (SE=Sweden, IS=Iceland, GB=Great Britain, IE=Ireland, US=United States, SG=Singapore). For details on the studies in each pair, see Table 1.
