Boxplots are displaying the crude cumulative incidence rates per district in each of the time periods, [period 1 (1995 to 1999), period 2 (2000 to 2004), and period 3 (2005 to 2009)] paneled by the dummy region: Central, East, Nakchivan, and West. Crude estimates were calculated for each period using the total number of reported cases during a 5-year period as the numerator and the median year population as the denominator.
