The problem
Intervention: No intervention was tested; this was an observational study examining the association between animal feces exposure/Giardia infection and child health outcomes
Who it was tested with: 639 children under 5 years of age in six districts across three Cambodian provinces (Phnom Penh, Kratie, Ratanak Kiri).
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.

The analysis included a sample of 639 children under 5 years of age." This is a longitudinal cohort study design with multiple follow-up rounds, meeting the criteria for experimental evidence tier.
