Figure 5From: Defining the relationship between Plasmodium vivax parasite rate and clinical diseaseViolin plot of incidence (per 1,000 person-years observed). A) all data (n = 388) by region and B) data used in the analysis (n = 176) by region are shown with incidence on the logarithmic scale. The grey areas correspond to a smoothed approximation of the frequency distribution (a kernel density plot) of the incidence observed in each geographic region. The black central bar represents the interquartile range and the white circles indicate the median values.Back to article page
