^*Perceived water quality: ‘good’ describing ‘colourless, odourless and transparent’ water and ‘poor’ if any of the criteria was not met.

^†Handwashing knowledge: index variable (good/poor), created from responses to two questions assessing the perceived necessity of using soap and the perceived potential for dirty hands to spread disease. ‘Good’ is describing guardians with an understanding of the relevance of using soap and of dirty hands spreading disease.

^‡Handwashing index: index variable (frequent/less frequent), developed by combining responses on the frequency of handwashing before eating and after using the toilet. ‘Frequent’ handwashing describes guardians who wash their hands more than half of the times before eating and after using the toilet.

^§Confidence in children’s handwashing behaviour: (high/medium or low) confidence of reporting guardian in their child’s knowledge of proper handwashing steps derived from a 5-point Likert scale.
