1
. These results are from changes to walking exposure alone. These are directly taken from HEAT Walking, comparing the results for mean baseline walking time versus the results for mean walking time under each Vision. They represent percentage reductions in disease burden in people aged <74 years.
2
. These results are from changes to cycling exposure alone. These are directly taken from HEAT Cycling, comparing the results for mean baseline cycling time versus the results for mean cycling time under each Vision. They represent percentage reductions in disease burden in people aged <65 years.
3
. The change in deaths/YLLs amongst the affected population (age <65 years walking, <75 years cycling) as a percentage of deaths in the whole population.
