What is a query in the context of clinical trials?

In the context of clinical trials, a query refers to a question or request for clarification regarding clinical data management. Queries are essential tools used by data managers and clinical researchers to ensure data accuracy and integrity. They might arise when discrepancies, missing information, or unexpected results are identified in the data collected during a trial. By formulating queries, clinical trial personnel can seek clarification or additional information from investigators, sites, or participants, ensuring that the data collected meets the study's requirements and that any issues are resolved promptly.

This understanding of a query as a communication mechanism for clarifying data highlights its pivotal role in maintaining the quality of data used in analyses and regulatory submissions. It helps ensure that the collected data is reliable and that the findings of the clinical trial are valid and reproducible.
