Periodic Identification of Notified TB Cases and Trend Prediction of TB in Zhejiang Province. (A) The identification of potential periodicity of TB notification. With the change of different lag, the scatter diagram showed an obvious linear trend at lag 12, implying a potential periodicity of 12 months; (B) Number of notified TB cases predicted by the SARIMA model. The TBIMS data in the study period was used as the training dataset to construct the model and predict notified TB cases with an 80% confidence interval (CI) and 95% CI in 2019. These figures were created by R software (3.5.3). URL http://www.R-project.org.
