case_images: Feedback scores from respondents completing the discrete choice experiment (DCE) and swing-weighting (SW).. White = Ease of understanding the DCE; Light grey = Ease of answering the DCE; Dark grey = Ease of understanding the SW; Black = Ease of answering the SW; Respondents answered on a scale from 1 to 6, 1 being the most difficult and 6 being the easiest; Low health numeracy scored below 9.83 (the mean) on the SNS-3; High health numeracy scored above 9.83 (the mean) on the SNS-3; Health literacy questions are scored 1-5 with the middle question inversed:Low health literacy identified by a score of >3 on any item; High health literacy scored <2 on any item (see Louis et al, 2016).

case_images: Overall, the DCE was reported by participants to be both easier to understand and to complete, compared to the SW (Fig 2).
case_images: Proportion of attribute importance relative to sum of all attributes' importance (DCE and SW calculated through both ROC and PA.. DCE = discrete choice experiment; SW = swing weighting; PA = point allocation; ROC = rank order centroid method.

case_images: For the DCE, the proportion of attribute importance is very different for all the attributes (Fig 3). Fig 3). Fingerprick frequency was the most important attribute (mean = 0.18; s.d. = 0.11), followed by cost (mean = 0.17; s.d. = 0.13), with alarm being the least important attribute (mean = 0.11; s.d. = 0.11). The ROC method for determining weights still achieved very little difference in the relative weights given to the seven attributes, (Fig 3).
