Epidemiology
Randomized controlled trials (RCTs) are experimental studies where participants are randomly assigned to either the intervention group receiving the treatment or the control group receiving a placebo or standard treatment. This method is essential in determining the effectiveness of new treatments or interventions, providing strong evidence due to the randomization process that minimizes bias. RCTs play a critical role in public health by informing evidence-based practices and policies, while also requiring careful consideration to reduce potential biases and accurately interpret findings.
