What should be included when reporting on data extraction in systematic reviews?

When reporting on data extraction in systematic reviews, it is crucial to include explicit details about the extraction methods used. This is important because transparency in the methodology allows other researchers to assess the reliability and validity of the extracted data. By detailing how the data was gathered, including any specific protocols or tools utilized, the review can support its findings with rigorous evidence. This information helps in evaluating how comprehensive and systematic the extraction process was, which ultimately contributes to the credibility of the systematic review's conclusions.

Including a thorough description of the extraction methods also aids other researchers in replicating the study or conducting future research, fostering a better understanding of the process involved in data synthesis. Therefore, this choice emphasizes the significance of methodological clarity, making it the correct answer for reporting on data extraction.
