Figure 2. Number of tuberculosis (TB) cases modeled with 0 and 1 significant changes in trend for all foreign-born persons and 0, 1, and 2 significant changes in trend for foreign-born persons from Mexico, 2000–2010.

Figure 2

Significant changes in trend were determined using Joinpoint analysis (Joinpoint version 3.5.2, Bethesda, MD http://surveillance.cancer.gov/joinpoint/). Arrows indicate the years in which significant changes in trend for foreign-born persons from Mexico occurred (blue arrow corresponds to model results with a single change in trend and red arrows correspond to model results with 2 changes in trend).
