Improvements to water purification and sanitation infrastructure may reduce the diarrheal burden in a marginalized and flood prone population in remote Nicaragua

Table 4 Linear regression models of the relationship between latrine use, latrine overflow, and diarrhea^A in the North Atlantic Autonomous Region, Nicaragua, 2009 (N = 189).

	Final PD^B(95% CI)	Full Multivariate Model^C PD (95% CI)
Latrine Use^D
No Latrine	0	0
Latrine, no overflow	-0.17 (-0.35, 0.01)	-0.17 (-0.36, 0.01)
Latrine, overflowed^E	0.02 (-0.18, 0.22)	0.03 (-0.18, 0.23)
Overflow
No reported overflow	0	0
Reported overflow	0.19 (0.03, 0.36)	0.20 (0.03, 0.36)

PD = prevalence difference
^A Two week prevalence of household diarrhea
^B The final model was not adjusted for other covariates
^C The full multivariate models were adjusted for tambos (a proxy for living in a flood prone region), number of individuals in the household, and education level of the head of household (a proxy for socioeconomic status of the household)
^D Household latrine
^E Within household that had a latrine, did that latrine overflow (1 or more times) in the past year.
