“…Iconoclasts have even questioned the value of early diagnosis in influencing the outcome of treatment of breast cancer, but the five-year follow-up figures from the Health Insurance Plan survey in New York (Strax et al 1970) surely convince one of the value ofearly diagnosis.…”

“…Following Mushlin and Fintor (1992), which I use for comparison, I set $100 as the cost of a mammogram, $900 as the cost per biopsy, and approximately $5 per screen as the expected treatment costs saved due to early detection. Based on work of Strax, Venet, Shapiro, Gross, and Venet (1970), 1.5% of women on the first screen, and .6% of women on each subsequent screen receive a biopsy. With a discount rate of r = 5%, the total discounted cost of four yearly screens is C = $382.…”

The purpose of a diagnostic efficacy study is to evaluate and compare the sensitivities and specificities of several diagnostic tests. Usually the diagnostic tests are correlated conditional on disease status, and the reference test is subject to error. In the Chlamydia trachomatis study, five screening tests for detecting chlamydia in endocervical specimens were compared. The five tests are correlated, and the reference test (the cell culture test) has less than 100% sensitivity. The conventional method ignores both the correlations between the tests and the misclassification of the reference test and thus cannot provide a valid analysis. We propose a model to evaluate and compare the sensitivities and specificities of correlated diagnostic tests when there is either an imperfect reference test or even no reference test. The model also can estimate the effects of covariates. It is a generalized linear mixed model with two unobserved variables, one continuous and one dichotomous. We use a hybrid algorithm, which consists of the EM algorithm and the Newton-Raphson method, for obtaining its maximum likelihood estimation. Methods for model checking and for estimating and comparing both subject-specific and population-averaged sensitivities and specificities are given.
