We found that 95.5% (95% CI 91.0%\u201497.9%) of respondents wished to know the trial results and the preferred method was through viewing summary posters via an online link (78.2%; 95% CI 71.1%\u201484.0%). Most felt satisfied after learning the trial results (67.8%; 95% CI 59.5%- 75.2%) and 82.2% (95% CI 75.2%\u201487.5%) wanted to know which treatment they received.
