Spatial distribution and populations at risk of A. lumbricoides and T. trichiura co-infections and infection intensity classes: an ecological study

Table 3 Spatial effects for the prevalence of mono- and co-infections in Mindanao

Coefficient	A. lumbricoides mono mean (95% BCI)^a	T. trichiura mono mean (95% BCI)^a	Co-infection mean (95% BCI)^a
Female vs male	0.11 (0.02–0.19)	0.12 (0.01–0.23)	0.19 (0.07–0.32)
Age 5–19 vs < 5 years-old	0.24 (0.11–0.38)	1.39 (1.16–1.63)	1.39 (1.20–1.59)
Age ≥ 20 vs < 5 years-old	-0.43 (-0.57– -0.29)	0.92 (0.70–1.16)	0.30 (0.10–0.51)
Normalised difference vegetation index^b	-0.01 (-0.21–0.19)	-0.23 (-0.53–0.06)	-0.52 (-0.86– -0.15)
Intercept	-1.87 (-2.08– -1.65)	-4.88 (-5.27– -4.38)	-3.57 (-3.97– -3.19)
Phi^c	65.9 (23.67–98.44)	0.10 (0.10–0.12)	50.6 (13.35–96.77)
Tau, precision	1.23 (0.88–1.65)	0.01 (0.01–0.02)	0.39 (0.27–0.53)

^aBCI Bayesian Credible Interval (The posterior distributions are summarized by the posterior mean and 95% BCI. A variable was considered as influencing the outcome if it excluded 0)
^bVariables were standardized to have mean of zero, and standard deviation of 1
^cRate of decay of spatial autocorrelation, measured in decimal degrees; 3/phi determines the cluster size; one decimal degree is approximately 111 km at the Equator (the size of the radii of the clusters)
