  • Respondents were not asked personal details that might identify them, and we did not ask where they lived. From the web strategy to avoid repetitive answering, we had the grid references of the computer used and from that were able to visualised the geographical distribution shown in onlineĀ supplementary file 2. This table is therefore an approximation because we did not obtain or attempt to work out the exact location of the respondent.
