The problem
Intervention: National laws prohibiting domestic violence, assessed by whether children were born after enactment or only partly exposed.
Who it was tested with: 38,955 African children aged 36–59 months.
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.
"Using a difference-in-differences design across 38,955 African children aged 36–59 months" shows a comparison-group, quasi-experimental design, which fits the experimental tier.
Only the abstract is available. It does not name the countries, describe the outcome measure or report robustness checks. The effect sizes are large and the abstract does not say whether they are plausible or what drives them.
