Boxplot of the effect of elevation site on the nymphal infection prevalence (NIP), which is the percentage of I. ricinus nymphs infected with B. burgdorferi s.l.. For each of the four elevation sites, the NIP values are shown for the 15 years of the study (2004–2018). Compared to the low elevation site, the NIP was 13.4%, 23.6%, and 9.4% lower at the medium, high, and top elevation sites, respectively. The boxplots show the median (black line), 25th and 75th percentiles (edges of the box), and minimum and maximum values (whiskers)
