Multivariate model 2 using logistic regression to determine associations between B. bacilliformis seropositivity including statistically significant variables from univariate analysis

Variablea	Odds Ratio (95% CI)	p b
Animal waste	0.47 (0.24, 0.91)	< 0.026
Lumber pile	2.47 (1.08, 5.63)	< 0.032
Elevation (per 100 m)c	0.76 (0.66, 0.87)	< 0.001

OR odds ratio, CI  confidence interval

^aAnimal waste was also included for biological importance as a sand fly breeding site and larval food source

^bStatistically significant at p < 0.05

^cThe odds ratio is 0.76 for each 100 m of elevation; the odds ratio decreases for each 100 m increase in elevation. This is consistent with the univariate analysis
