The design and analysis of randomized controlled trials

  • What is the design of randomized controlled trials?

    DESIGN OF A RANDOMIZED CONTROLLED TRIAL
    An RCT is a prospective study following patients forward in time.
    After agreeing to participate, patients are randomly allocated to one or more interventions or a control group and are followed until a finite date or the occurrence of one or more outcomes of interest..

  • What type of research design is a randomized controlled trial?

    In summary, randomized controlled trials are quantitative, comparative, controlled experiments in which a group of investigators studies two or more interventions by administering them to groups of individuals who have been randomly assigned to receive each intervention..

  • In randomized controlled trials, trial participants are randomly assigned to either treatment or control arms.
    The process of randomly assigning a trial participant to treatment or control arms is called “randomization”.
  • Randomized controlled trials and impact evaluations in general play a critical role in evidence-based policy making.
    They provide an objective assessment of planned, ongoing or completed projects, programs or policies and give policymakers insight into what works and what doesn't in different contexts.
Design and analysis of randomized clinical trials requiring prolonged observation of each patient. I. Introduction and designAbstractPublication types.
In the RCT, the analysis must include an unbiased comparison of the groups produced by the process of randomisation, based on all the people who were randomised 

Can a randomized controlled trial generate high-quality evidence?

High-quality evidence can be generated by performing an randomized controlled trial when evaluating the effectiveness and safety of an intervention

Furthermore, randomized controlled trials yield themselves well to systematic review and meta-analysis providing a solid base for synthesizing evidence generated by such studies

What is a randomized controlled trial?

The randomized controlled trial is the most rigorous and robust research method of determining whether a cause-effect relation exists between an intervention and an outcome

High-quality evidence can be generated by performing an randomized controlled trial when evaluating the effectiveness and safety of an intervention

What is data analysis for randomized controlled trials for non-mathematical researchers?

Gives an overview of data analysis for Randomized Controlled Trials for non-mathematical researchers Provides extensive examples and datasets for the statistical methods discussed in the book This book provides a practical guide to the analysis of data from randomized controlled trials (RCT)
