| 本文回顾了偏倚风险的概念，将系统综述中的偏倚风险评价与证据质量、方法学质量、报告质量、精确性、外部真实性等方面的评价作了对比，然后讨论了偏倚风险评估工具的进展、工具本身存在的不足、以及工具使用的常见问题等，以帮助我国系统综述者更好地理解偏倚风险评估及其工具的使用。 |
| English Abstract: |
| This paper reviews the concept of risk of bias, followed by demonstrating why assessment of risk of bias in systematic reviews should be different from that of quality of evidence, methodological quality, reporting quality, precision, and external validity. We also discuss the recent development of tools for risk of bias assessment, the problems with the tools themselves, and the challenges in using these tools. This review may help systematic reviewers understand risk of bias assessment and the use of assessment tools. |
