AOR = adjusted odds ratio; CI = confidence interval; HWT = household water treatment. Hosmer and Lemeshow test of the final step was 0.74 (i.e., P > 0.05) and the test result of variance inflation factor was < 10. Therefore, the actual test result confirmed that no multi colinearity was observed.
Statistically significant at *P < 0.05; **P < 0.01; ***P < 0.001.
