Temporal changes of RTI risk of women of childbearing age in Bangladesh. a depicts the pixel-level percentage change of RTI risk of women of childbearing age in Bangladesh from 2007 to 2014, calculated as the median estimated prevalence for 2007 minus that for 2014 and divided by that for 2007 in each grid; b presents the district-level temporal trends in the three survey years. The decreasing areas were defined as the districts with prevalence significantly decreased compared with the previous survey year (i.e., median of posterior estimated prevalence was less than the lower bound of 95% BCI of posterior estimated prevalence in the previous survey year). Similar definition was defined for the increasing areas. And the areas with predicted prevalence that did not significantly increase or decrease were considered as the stable areas
