Fig. 3From: Spatial heterogeneity of malaria in Ghana: a cross-sectional study on the association between urbanicity and the acquisition of immunityAssociation between urbanicity and age, and MPF and age. The Figure illustrates an association between urbanicity and the mean age of malaria patients in months (a R2 0.27; p = 0.004), while there is no association between urbanicity and mean age of all patients (b R2 = 0.03; p = 0.21). In addition, there is an association between MPF and mean age of malaria patients (c R2 = 0.27; p = 0.004) and no association between MPF and mean age of all patients (d R2 = 0.08; p = 0.09). Data points are scaled proportional to the number of individuals contributing to the measurement of mean ageBack to article page
