Figure 4

Variable spatial effect of predicted adjusted odds ratios (AOR) for P. falciparum and P. vivax infection derived from generalised additive models (GAM) in Mirap. Base model covariates age, sex, LLIN usage and NDVI were applied in the GAM for 2014 and 2016 (a,b,d,e). Base model covariates combined with household covariates (extended model) were applied in the GAM in 2016 (c,f) to investigate the contribution of household risk factors to spatial risk. Spatial distribution of sampled households shown in grey points in both the 2014 and 2016 base models. Mirap is a coastal village, thick grey lines represent the coastline and thin black lines represent the main road. Maps were created in R v.3.6.2 (https://www.R-project.org/).
