Primary outcomes were healthier\n v<\/jats:italic>\n . less healthy main meal selected and total kilocalories (kcals) selected.\n <\/jats:p>\n <\/jats:sec>\n \n Setting:<\/jats:title>\n Participants selected a hypothetical evening meal from out-of-home food outlets on a simulated online food delivery app.<\/jats:p>\n <\/jats:sec>\n \n Participants:<\/jats:title>\n \n N<\/jats:italic>\n 3106 adult participants from the UK were randomised into taxation (\n n<\/jats:italic>\n 750), subsidies (\n n<\/jats:italic>\n 808), a combination of taxation and subsidies (\n n<\/jats:italic>\n 769), and standard pricing (\n n<\/jats:italic>\n 779). 57\u201358 % of participants were of higher SEP.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n There were no statistically significant effects of the pricing interventions on whether a healthy\n v<\/jats:italic>\n . less healthy main meal was selected (e.g. taxation\n v<\/jats:italic>\n . control OR 0\u00b791 (95 % CI 0\u00b774, 1\u00b712); subsidies\n v<\/jats:italic>\n . control OR 1\u00b708 (95 % CI 0\u00b789, 1\u00b731)) or on total kcals selected (e.g. taxation\n v<\/jats:italic>\n . control regression coefficient \u221244\u00b731 (95 % CI \u221295\u00b790, 7\u00b728); subsidies\n v<\/jats:italic>\n . control regression coefficient \u22127\u00b794 (95 % CI \u221260\u00b723, 44\u00b735)).
