↵a Acceptability score is the mean of all 13 individual items, with scoring reversed for the positive items (11: accurate, 12: control, 13: good use of time). Lower scores indicate better acceptability. Ratings: 1 = strongly disagree. 2 = disagree. 3 = disagree slightly. 4 = unsure or not applicable. 5 = agree slightly. 6 = agree. 7 = agree strongly. BP = blood pressure. IQR = interquartile range.
