- the calculations are based on published data of the DPS [11]:
- • sample size n = 468 individuals
- • compliance (having achieved ≥ 3 goals) = 117 individuals
- • 113 of the 117 compliant subjects had the desired outcome (no diabetes)
- • 273 of the 351 non-compliant subjects had the desired outcome
- • compliance in the intervention group: 87 of 235 subjects E = ((113/117) - (273/351)) × (87/235) = 0.07
- 1/E = 14.3*
- *At US$ 2,800 for a 3-year intervention, the prevention of one case of diabetes would cost 2,800 Ă— 14.3 = US$ 40,040
