Ecological association between jhum cultivation and malaria incidence at the study cluster level. The percent of individuals participating in jhum cultivation and monthly symptomatic P. falciparum incidence were calculated for each study cluster and compared using linear regression analysis from May of 2010 to August of 2012. The percent of the population practicing jhum cultivation and symptomatic P. falciparum incidence were statistically associated (R2 = 0.417; P < 0.001) at the study cluster level.
