For effective literature review, what is crucial for a researcher to maintain?

Maintaining consistent search parameters is essential for an effective literature review as it allows researchers to ensure that the results they obtain are relevant and comprehensive. Consistent search parameters involve a well-defined strategy for identifying sources of information, which might include specific databases, keywords, and inclusion or exclusion criteria. This consistency fosters reproducibility and reliability in the research process, enabling other researchers to follow the same path and validate or build upon the findings. It also aids in reducing bias in the selection of literature, ensuring that the review reflects a systematic approach to gathering and evaluating existing evidence. Such rigorous methodology is critical in evidence-based practice, where the credibility of sources directly impacts clinical decisions and outcomes.
