Significance of Non-randomized trial
A non-randomized trial is a type of clinical study where participants are assigned to treatment or control groups based on predetermined criteria rather than through random selection. This method of assignment can occur for various reasons and may introduce bias into the results. Non-randomized trials differ from randomized studies, as they do not involve random assignment, which can impact the reliability and validity of the findings.
