*
The difference was calculated as INDDEX24 minus PAPI.
†
Composite nutrient intake is calculated as the overall average of the average percentage accuracy of PAPI (or of INDDEX24) in estimating intake for energy, fat, protein, carbohydrate, fibre, vitamin A, vitamin C, Ca, Fe and Zn relative to intake based on the weighed food record.
‡
These scenarios assume the specified percentage of dietary data inputs (e.g. food composition data, standard recipes, conversion factors) can be borrowed from existing dietary reference data in the INDDEX24 database.
