The secondary data analysis approach is appropriate for evaluating historical trends and outcomes. However, while descriptive statistical methods such as proportions, rates, and ratios are mentioned, no specific mention of inferential statistical techniques or detailed epidemiological methods is provided. Critical definitions like "severe acute malnutrition" and "screening coverage" are implied but should be explicitly stated. The study could improve by specifying inclusion/exclusion criteria and clarifying analytical tools beyond just naming software packages.
