Systematic reviews are designed to provide a comprehensive and unbiased synthesis of research evidence. One of the crucial aspects of conducting a systematic review is the quality assessment of the studies included in the review. This quality evaluation is typically performed independently, meaning that multiple reviewers assess the studies separately to ensure objectivity and reliability in evaluating their methodological quality. This independent approach helps to minimize bias and ensures that the conclusions drawn from the review are based on the best available evidence.

Options that suggest only published studies are included, that only one reviewer's perspective is used, or that the focus is only on quantitative data do not accurately reflect the principles of systematic reviews. A systematic review can and often does include both published and unpublished studies to mitigate publication bias. Moreover, these reviews typically involve a team of reviewers to incorporate multiple perspectives and different types of data, including both qualitative and quantitative, to provide a more well-rounded synthesis of findings. Thus, the statement about independent quality assessments is a fundamental principle of systematic reviews.
