Detailed explanation-1: -Locascio. Randomized controlled trials (RCT) are prospective studies that measure the effectiveness of a new intervention or treatment.
Detailed explanation-2: -There are two types of intervention studies: randomised controlled trials and non-randomised or quasi-experimental trials. The randomised controlled trial is considered to be the gold standard of clinical research because it is the only known way to avoid selection and confounding biases.
Detailed explanation-3: -The randomized allocation of subjects ensures that both known and unknown determinants are evenly distributed among the different study groups. This minimizes bias in assessment of differences in effects between two or more treatment alternatives.
