†The number indicates how many different antibiotic substances were included. Where possible, we also included different modes of administration for the same substances to maximise the chances of recognition by respondents; however, these fine-grained differences are not explicitly represented in our quantitative analyses to avoid overcomplication. See online supplemental material for breakdown of drug bag contents by antibiotic substance and mode of administration.
