DALYs, disability‐adjusted life years; GBD, Global Burden of Disease Study.

^aReflect the severity of the disease sequelae with 0 representing perfect health and 1 representing death.

^bUsed a weight representing an overall average for skin disease across more finely disaggregated strata/severity levels.

^cUsed a weight representing an overall average for visual morbidity (i.e. the weight was not stratified by ‘low vision’ and ‘blindness’).

Where relevant additional studies that were not performing economic evaluations were included for comparison.
