A

Answer to Question 2

A
Feedback:
Methodologically, the main design issue in quantitative studies is whether the research design provides the most valid, unbiased, and interpretable evidence possible. Indeed, there usually is no other aspect of a quantitative study that affects the quality of evidence as much as research design. RCTs are the gold standard for intervention studies (Therapy questions) because they yield the highest-quality evidence about the effects of an intervention. Therefore, the best recommendation would be to follow the recommendations from the national randomized controlled trial because it is more authoritative than the quasi-experimental trial.
