A Randomized Controlled Trial (RCT) is a scientific research method used for efficacy evaluation and is a rigorous approach for causal inference. Primarily used in the medical field, RCTs are employed to investigate the effects of specific interventions, such as the introduction of new drugs or treatments. By randomizing the process, RCTs eliminate the influence of uncontrolled hidden factors, ensuring that the results can be attributed specifically to the interventions. This method provides a higher level of evidence compared to other types of studies, such as case studies or time-series analyses.

In an RCT, participants are randomly divided into multiple groups, each receiving different interventions. One group receives the specific intervention whose effect is to be measured, while the other receives either an existing method or a placebo. The results from both groups are then statistically analyzed to assess the effects of the interventions.

Because RCT is a methodology, it can be applied not only in medicine but also in other fields of research and business, including research and development and marketing. Our company conducts RCTs across various sectors and provides comprehensive services essential for RCTs, from experimental design to participant selection and data analysis and validation. We leverage our extensive Human Information Database, which contains a wealth of long-accumulated customer insight data, and our web survey system for monitors, allowing for the rapid and efficient dispatch of participants required for RCTs.

Our consulting approach encompasses three main steps: experimental design, subject dispatch, and analysis & validation. Based on the critical PICO framework (Population, Intervention, Comparison, Outcome) used in intervention studies like RCTs, we provide detailed experimental designs that leverage our expertise across various fields.

Firstly, in conducting an RCT, we formulate the most effective and efficient research plan and experimental setup. We thoroughly examine how to select participants, how to represent intervention outcomes, and the best ways to compare multiple groups, ensuring the study's foundation is robust.

For participant dispatch, we use our extensive monitor database and web survey system to quickly and reliably secure suitable subjects. Particularly with our Human Information Database, we maintain extensive data on people's characteristics and habits, allowing us to meet complex criteria and ensure a sufficient number of participants for reliable statistical analysis.

In the final stages of analysis and validation, our statistical experts perform data analysis to extract valuable insights crucial for research development and marketing strategies. This comprehensive and integrated approach supports our clients in achieving their research and business objectives.
