Fig. 2From: Spatial heterogeneity of malaria in Ghana: a cross-sectional study on the association between urbanicity and the acquisition of immunityAssociation between urbanicity and MPF. The Figure illustrates a linear decrease of MPF with increasing levels of urbanicity. The linear regression models a 5 % decrease per ten-point increase on the urbanicity scale (95 % CI: 4–6 %, R2 = 0.70, p < 0.001). Data points are scaled proportional to the number of individuals contributing to the measurement of MPFBack to article page
