Figure 1

Graphical respesentation of a six-state parameter estimation model and a10-state overdiagnosis model. This figure shows states included in theparameter estimation model, a six-state Markov model of breast cancerprogression for estimating screening parameters including screening testsensitivity and mean sojourn time, and the overdiagnosis model, an extended10-state model aimed at estimating the extent of overdiagnosis. Dotted statesare those added in the extension from the former to the latter model. Thescreen-detected in situ state groups two distinct states:screen-detected progressive and non-progressive in situ.
