What is the consequence of failing to comply with protocol during a clinical trial?

The consequence of failing to comply with the protocol during a clinical trial primarily leads to compromised validity of the study results. Adherence to the study protocol is critical as it outlines the methodology, participant criteria, and treatment procedures necessary to ensure the trial’s integrity and reliability. Any deviations can introduce biases, confound results, or affect the overall consistency of the data collected. This can result in misleading conclusions about the safety and efficacy of the intervention being tested, thus undermining the purpose of the trial.

In clinical research, protocols are designed based on prior knowledge, scientific principles, and regulatory requirements to minimize risk and enhance the quality of the data. When the protocol is not followed, it can lead to inconsistencies that challenge the credibility of the findings, making it difficult to determine whether observed outcomes are attributable to the treatment or influenced by uncontrolled variables.

The other options would not accurately reflect the primary consequences of protocol non-compliance. For example, rather than improved participant retention rates, failing to comply may actually lead to increased drop-out rates due to dissatisfaction with the trial process. Increased trial complexity is not a direct outcome of non-compliance; rather, non-compliance typically complicates the interpretation of results. Lastly, non-compliance does not lead to unrestricted access
