A systematic review is a powerful tool to synthesize and show concise and robust evidence for clinical practice. Thus, the inclusion of biased, low-quality studies should be avoided, for otherwise, the resulting systematic review will not reflect the best medical evidence. Because the methodology of systematic review is relatively new, this review aims to present basic rules to guide the reader's interpretation of a systematic review.

系统评价是一种强大的工具，可综合并展示用于临床实践的简洁而有力的证据。因此，应避免纳入有偏倚、低质量的研究，否则，由此产生的系统评价将无法反映最佳医学证据。由于系统评价的方法相对较新，本综述旨在提出基本规则，以指导读者解读系统评价。
