Surprisingly, the application of our simple software based on a slightly modified perspective allowed us to extract some original information about complex phylogenetic problems.
From the health system perspective, from the modified societal perspective, and from the societal perspective, lifestyle cost more than placebo but was also more effective as assessed by the QALYs that were gained.
We included direct nonmedical costs excluding participant time in a sensitivity analysis from a modified societal perspective and direct nonmedical costs including participant time in a sensitivity analysis from a full societal perspective.
Outcome measures were assessed from a modified societal perspective and life expectancy, quality-adjusted life expectancy, and costs (2007 €) were discounted at a rate of 3% per annum [14].
For stigma expectations we expect no association, in accordance with the modified labelling perspective.
Thus, according to the modified labelling perspective, stigma expectations can produce negative consequences even if no direct social rejection or discrimination takes place.
Following the literature review, we decided upon a prevention-only model and a modified provider perspective such that the costs of treating malaria were excluded.
For the base-case we adopted a modified societal perspective and discounted future costs and disability-adjusted and unadjusted life years by 3% annually [ 12- 15].
The modified labelling perspective, for example, states that negative societal attitudes become personally relevant and are translated into a concrete fear of devaluation and discrimination when persons receive psychiatric services [ 17, 18].
We used decision analysis based on data from the literature to evaluate cost-effectiveness from a modified societal perspective over patients' lifetimes, with outcomes expressed as incremental costs per quality-adjusted life-year (QALY) gained.
