For all data, percentages (%) are based on the total number of responses to each question as the denominator, which may vary. Age was not approximately normally distributed; thus, median and inter-quartile range (IQR) are reported in addition to mean and standard deviation (SD).
Levels of education were specific to each region (i.e., Belgium, Singapore, or the US); responses are reported according to US categories.
Income ranges were specific to each region’s respective currency (e.g., Euros in the Belgian questionnaire; Singapore $ in Singapore) and are reported in US categories.
Participants in Singapore and the U.S. (but not Belgium) were asked how they paid for their health care; participants were asked to select all that apply, so multiple options were applicable.
