Schematic of TB simulation model. The schematic shows compartments within each dimension of the model: a Main model: core TB dimensions; b Age group dimension; c Gender dimension; d Risk group dimension by migration status. Arrows identify entries to the model and possible transitions between compartments. Solid arrows indicate state transitions, dotted arrows indicate model entry for resident individuals, and dashed arrows indicate model entry for internal migrant individuals. Migrants were divided into different status based on their duration of staying in Shanghai. Migrants exits due to death are not shown
