What would be required to disprove reverse causality? They discuss it more than twice > In other words, an outcome assessed at visit v was regressed on low-calorie sweetener history up to the visit prior to outcome assessment to rule out reverse causality. In Model 2, outcomes at visit v were regressed on low-calorie sweetener use history through visit v-1, hence minimizing reverse causality.
