Cost-effectiveness analysis order is from the lowest-cost strategy to the highest-cost strategy. Model 1=trained research assistants (RAs) directly delivered the RLPL games to children; Model 2=trained RAs trained trainers, who then trained teachers to deliver the RLPL games to children; Model 3=program faculty trained teachers, who then delivered the RLPL games to children.
