Figure 5: Characteristics of the Duffy negativity phenotype in Africa.

From: The global distribution of the Duffy blood group

Figure 5

This figure shows the covariate line (in green), which separates sub-Saharan African populations from the rest of the continent; hatched areas indicate areas of confidence in the distribution of ≥95% Duffy negativity frequency: with 75%and 95% confidence. Black data points correspond to the input Duffy data points (n=821). Yellow stars indicate locations of P. vivax-positive community surveys (n=354), and blue stars P. vivax-negative surveys (n=1405) (data assembled by the Malaria Atlas Project17,46). Supplementary Figure S7 is a greyscale image of this figure.
