ICER Incremental Cost-Effectiveness Ratio
Negative values indicate cost savings compared to the preceding strategy
^aA strategy is dominated when it is both more costly and less effective than the preceding strategy
^bThe food insecurity reduction strategy is compared to the tobacco reduction strategy because the heavy drinking strategy is dominated. Because of this, the food insecurity strategy is dominated as well, due to extended dominance
^cThe combination of food insecurity reduction and smoking reduction is preferred to food security reduction alone, because of extended dominance. For that reason, incremental values are listed in comparison to the tobacco reduction strategy
