Evaluation 1 of "Water Treatment and Child Mortality: A Meta-analysis and Cost-effectiveness Analysis"

We evaluated the conduct, analysis and interpretation of the meta-analysis findings. The paper concerns an important topic for the global burden of infectious disease, particularly in middle-income countries where most of the included studies were conducted. It presents useful information on childhood mortality following water treatment and protection interventions. However, we had major concerns about conduct and reporting, which did not follow systematic review standards of transparency, and we also had major concerns about the interpretation of the findings for policy and research.
