The reliability of systematic reviews for decision-making depends on the quality of evidence provided by primary studies, as well as on the methodological rigor of the reviews themselves. Well-developed, publicly available systematic review protocols support high-quality implementation, reduce the risk of bias, enhance transparency, and avoid unnecessary duplication. However, limited evidence exists regarding how systematic reviews in the nutrition field are planned and documented. Therefore, the aim of the study is to assess the planning process of nutrition-related systematic reviews.

The results of clinical trials are often only partially transferable to everyday clinical practice. To address this limitation, pragmatic clinical research and analyses based on routinely collected healthcare data are gaining increasing importance. The aim of our study is to comprehensively evaluate the characteristics, applicability, effectiveness, and dissemination of these types of investigations.

Interventions that fall outside formal regulatory oversight, such as nutrition, exercise, surgical, behavioral, and alternative medicine approaches, are frequently investigated for their potential to improve health outcomes. Because these interventions often involve multiple components and vary in delivery, rigorous trial design and clear reporting through published protocols or registry platforms are essential for scientific validity. A well-documented protocol allows researchers to evaluate the planned methodology and later compare it with published results. When key details are missing, trials become harder to appraise, replicate, and include in systematic reviews. Examining published protocols or registry platforms can reveal recurring gaps in trial design and reporting. Therefore, before addressing these gaps, it is necessary to first identify and characterize them systematically across both protocol publications and registry records. This systematic identification can strengthen the evidence base that informs clinical decision making.

Research conducted in emergency care involves several specific challenges, including time-critical decision making, limited possibilities for patient follow-up, and strict ethical requirements. The defined research topic focuses on identifying and developing research methods that are suitable for addressing these difficulties.
