Biostatistics
A randomized controlled trial (RCT) is a scientific study design that randomly assigns participants to either a treatment group or a control group, allowing researchers to assess the effectiveness of an intervention. This method minimizes bias, ensuring that differences in outcomes can be attributed to the treatment rather than other factors. The power of RCTs lies in their ability to produce strong evidence for causal relationships and their role in determining effect sizes and statistical power for further analyses.
