The purpose of including primary and secondary endpoints in a protocol is to:

Including primary and secondary endpoints in a research protocol serves to clarify the research objectives and outcomes. Primary endpoints are the main outcomes that the study aims to assess, providing the most critical data necessary to evaluate the effectiveness or impact of an intervention. These endpoints directly align with the study's hypotheses and overall goals, allowing researchers to determine whether the intervention meets its intended purpose.

Secondary endpoints, on the other hand, offer additional insights beyond the primary outcomes. They can provide information about other effects of the treatment, assess safety, or explore various subgroups within the study population. By clearly defining both primary and secondary endpoints, the researchers ensure that the study has well-established metrics for success and can effectively communicate the findings to stakeholders, including regulatory bodies and the scientific community.

The clarity brought by these endpoints also aids in the design and analysis phases, as well as in the interpretation of results, helping distinguish between outcomes that are essential for the main research question and those that provide supplementary data. This comprehensive outline of objectives and measureable outcomes enables a structured approach to evaluating the effectiveness and impact of the study.

In contrast, outlining financial distributions, detailing steps in data collection, and specifying methodologies are important aspects of a research protocol, but they do not primarily focus on the objectives and
