The DTP efficiency at 100% CF efficiency improves to nearly three times (78.9%) the value attainable for CF efficiency at 33%, at the current rates of compliance (column 2, last rowofTable6b). Compliance, regimen mixes, CF efficiency and DTP efficiency Another factor that could be studied through the model is the effect of varying the mixes of relative proportions of cases on SR and SCC. The DTP efficiency at varying efficiencies of casefinding, computed by varying hypothetically the proportions of regimen mixes and compliance structure by levels is given in Table 7. Only a few compliance structures are shown, with one currently seen in an operational study and another with all the cases complying at 100% at level 4, and two others with arbitrarily imputed values, in order to illustrate the dynamics. One of the latter two alternatives (structure 'b' in Table 7) is a close approximation of the situation in a DTP with the best treatment compliance 9 . The DTP efficiency increases by about 10%, if all the cases are put on SCC instead of SR, at the current
