A review of research reveals two articles that have conflicting results. A national randomized controlled trial found that annual brain scans will allow early detection and treatment of brain cancers, reducing mortality by 65%. An international quasi-experimental trial reported no significant reduction in mortality with annual scans. Based on your review, propose the best recommendation

A). Recommendations from the national study should be followed.

Explanation:

As per the question, option A i.e. 'recommendations from the national study should be followed' proposes the best recommendation. The chief concern in quantitative studies is if the research offers authentic, objective, reliable evidence possible and the research design is the most significant aspect that influences the standard of evidence. Therefore, the most appropriate recommendation would be to consider the 'recommendations from the national studies which offer randomized controlled trial' as it is considered high-quality evidence and more authoritative than the quasi-experimental trial. Thus, option A is the correct answer.
