Fig. 5: molFOI does not concentrate in geographic hotspots.

a Visualization of homes and molFOI in Kalifabougou, Mali. Each dot represents the geographic coordinates of one participant’s home, colored by their molFOI in 2011. Points are slightly jittered, for visibility. Black lines represent local rivers, geospatial data from Global Map of Mali © ISCGM/IGM. b Scatter plot of each participant’s molFOI in 2011 (x-axis) vs. the distance from their home to the Kalifabougou clinic (y-axis, labeled in kilometers) (quasi-Poisson regression, two-sided t test; t(312) = 5.71, P = 2.68e−8, β = 0.00021 [95% CI: 0.00014–0.00028]). The line shows the linear regression (adjusted R2 = 0.089, P = 4.3e−8). c A similar scatter plot to (b), except that the y-axis shows the distance from each participant’s home to the nearest river (quasi-Poisson regression, two-sided t test; t(312) = 3.00, P = 0.003, β = 0.19 [95% CI: 0.066–0.32]). Linear regression shown as described above (adjusted R2 = 0.025, P = 0.0031). CI confidence interval, molFOI molecular force of infection.
