Comparison of gross domestic product (GDP) per capita by importation of yellow fever during 2017–18 epidemic (n = 86). GDP per capita is compared between countries with and without imported cases (n = 8 and 78, respectively) that were included in our analysis. Mid bold line in the hinges represents median value. The lower and upper hinges correspond to the first and third quartiles. The upper whisker extends from the hinge to the largest value no further than 1.5 times interquartile range, and the lower whisker extends from the hinge to the smallest value at most 1.5 times interquartile range
