Randomization in a clinical trial refers to the process of randomly assigning participants into different groups, which may receive different treatments or interventions. This is done to ensure that the assignment of participants is unbiased and not influenced by any external factors.
In some trials, participants may be randomly assigned to a "control group" that receives either no treatment or a standard treatment already available in the market, while other participants may be assigned to a "treatment group" that receives the investigational treatment being studied.
Randomization helps to eliminate potential bias and ensures that the results of the trial are valid and reliable. The study staff will provide you with more information about the different groups and treatments being investigated in your specific trial.
