A simplified guide to randomized controlled trials

Area of Science:

• Clinical Research Methodology
• Evidence-Based Medicine
• Biostatistics

Background:

• Randomized controlled trials (RCTs) are prospective, comparative studies with random intervention allocation.
• RCTs are the most rigorous method for establishing cause-effect relationships between interventions and outcomes.
• High-quality evidence from RCTs is crucial for evaluating intervention effectiveness and safety.

Purpose of the Study:

• To provide descriptive guidance on the planning, conducting, analyzing, and reporting of randomized controlled trials.
• To address the practical challenges associated with designing and executing RCTs.
• To support the increasing use of RCTs in clinical medicine, including perinatology.

Main Methods:

• The study is a review providing descriptive guidance.
• Focuses on the practical aspects of RCTs from inception to dissemination.
• Emphasizes the importance of systematic review and meta-analysis for RCT data.

Main Results:

• RCTs provide a solid base for systematic reviews and meta-analyses.
• Evidence-based clinical practice, supported by RCTs, improves patient outcomes and safety.
• RCTs are increasingly utilized across clinical medicine due to their robustness.

Conclusions:

• Randomized controlled trials are essential for generating high-quality clinical evidence.
• Effective planning, execution, and reporting are critical for successful RCTs.
• This guidance aims to simplify the process of conducting rigorous RCTs.
