Outcome duration was life long and treatment side-effects were not included. Costs and benefits were discounted at 5%.
Incremental cost per life year gained for women with bone density <0.9g/cm2 was 9130 and for women with bone density <1.0g/cm2 was 17300.
Incremental cost per QALY gained for women with bone density <0.9g/cm2 (16.6% of women) was 3280 and for women with bone density <1.0g/cm2 was 6710.
The range of incremental cost per life year gained for women with bone density <0.9g/cm2 was: negative incremental costs and positive incremental benefits (lowest value) and highest value was greater than 133,000. For women with bone density <1.0g/cm2 the lowest value was 17,250, and highest value was 133,000.
The range of incremental cost per QALY gained for women with bone density <0.9g/cm2 was negative incremental costs and positive incremental benefits (lowest value); the highest value was 50,400. For women with bone density <1.0g/cm2 the lowest value was 6710, and the highest value was 50,400. Sensitive parameters were relative risk of hip fracture.
