A majority of participants (53.1%) chose public data release as their final data sharing decision, a third (33.1%) chose restricted release, and the remaining individuals (13.7%) chose no release (Table 3). Final data sharing decisions and whether this choice differed from their original selection were significantly associated with randomized consent type (final decision chi-square test, p=.02; changing decision chi-square test, p=.01). Those randomized to traditional consent were most likely to choose public data release as their final data sharing decision (62.1%). Only 6% of participants randomized to traditional consent chose not to release their data at all, compared to nearly 20% of those randomized to either binary or tiered consent. Participants randomized to tiered consent were less likely to change their data sharing decision before and after debriefing. 78.8% of those randomized to tiered consent changed in their final data release selection compared to 62.1% randomized to traditional consent and 62.3% randomized to binary consent.
