The paper extended the previous model by adding the effect of the permanent resident on the migrants. The numerical simulation indicated that the basic reproductive numbers should be less than one in permanent residents and migrants in order to eliminate disease from the population. Evaluation on the TB-Screen Strategy of Canada showed that the epidemic of TB was sensitive to the TB control strategies.
Model-based meta-analysis (MBMA) is a new type of quantitative analysis method, random effects in statistics will be found and put into the model as well as covariates. The final model has a strong predictive ability, can be conducted to make clinical decisions and evaluation. For its complexity, MBMA study is difficult to perform which restricted its application. By summarizing current published MBMA studies as well as the authors' experience, this article introduced the principle, method and status of MBMA.
