Aggregated attributable fractions for diarrhoeal risk factors among children younger than 5 years by GBD super-region, 2017

In the comparative risk factors framework used in GBD 2017, risk factors are counterfactual and can overlap such that a single risk might be sufficient, but is not necessary, to cause a diarrhoea death. Therefore, although the total risk attribution cannot exceed 1, there could be overlap between the risk factors associated with rotavirus vaccine coverage, ORS treatment, nutrition, or WASH at the population level, such that eliminating exposure to one would avert a diarrhoea death. ORS=oral rehydration solution. WASH=water, sanitation, and hygiene.
