Randomized Controlled Trial (RCT) Overview
A randomized controlled trial (RCT) is a prospective experimental design that randomly assigns participants to an experimental or control group. RCTs are the gold standard for establishing causal relationships and ruling out confounding variables and selection bias. Researchers must be able to control who receives the treatments and who are the ...

Designing and Conducting Randomized Controlled Trials: Basic Concepts
An RCT is a quantitative, comparative and a controlled experimental study in which the researcher allocates people at random to receive one of several clinical interventions and then observes its effect on a pre-decided clinical outcome. Clinical trials are performed with a purpose of assessment of efficacy, safety, or risk benefit ratio.
A simplified guide to randomized controlled trials
Abstract. A randomized controlled trial is a prospective, comparative, quantitative study/experiment performed under controlled conditions with random allocation of interventions to comparison groups. The randomized controlled trial is the most rigorous and robust research method of determining whether a cause-effect relation exists between an ...

Randomized Controlled Trials
Randomized controlled trials (RCTs) are considered the highest level of evidence to establish causal associations in clinical research. There are many RCT designs and features that can be selected to address a research hypothesis. Designs of RCTs have become increasingly diverse as new methods have been proposed to evaluate increasingly complex ...

Randomized Clinical Trial (RCT): Simple Definition, Phases, and Types
Experiments that use cluster randomization are sometimes called cluster randomized trials (CRTs) or group-randomized trials. When to Use CRTs. CRTs are often used to measure the effectiveness of management strategies and public health interventions. They are sometimes used in a clinical setting to study drug effectiveness (Mazor et. al, 2007).

Introduction to Field Experiments and Randomized Controlled Trials
Field experiments, or randomized studies conducted in real-world settings, can take many forms. While experiments on college campuses are often considered lab studies, certain experiments on campus - such as those examining club participation - may be regarded as field experiments, depending on the experimental design. ...

The Methodologies section in particular should clearly explain how the participants were sorted into group. If the author states that participants were randomly assigned to groups, then that study is a Randomized Control Trial (RCT). If nothing about randomization is mentioned, it is safe to assume the article is not an RCT.
