Sankey diagram identifying the flow of corruption across the food system areas and its eventual impacts. The width of each flow is proportional to the total number of concepts identified in the literature for that node, representing a salience of these concepts across the literature base. As the categories for the different nodes are not mutually exclusive the totals vary between nodes. For Node 3, the NA category represents papers that did not report on the impacts of corruption and were classified as ‘descriptive’ studies
