OBJECTIVE
Grading of recommendations, assessment, development, and evaluations (GRADE) is arguably the most widely used method for appraising studies to be included in systematic reviews and guidelines. In order to use the GRADE system or know how to interpret it when reading reviews, reading several articles and attending a workshop are required. Moreover, the GRADE system is not covered in standard medical textbooks. Here, we explain GRADE concisely with the use of examples so that students and other researchers can understand it.
BACKGROUND
In order to use or interpret the GRADE system, reading several articles and attending a workshop is currently required. Moreover, the GRADE system is not covered in standard medical textbooks.
METHODS
We read, synthesized, and digested the GRADE publications and contacted GRADE contributors for explanations where required. We composed a digested version of the system in a concise way a general medical audience could understand.
RESULTS
We were able to explain the GRADE basics clearly and completely in under 1500 words.
CONCLUSIONS
While advanced critical appraisal requires judgment, training, and practice, it is possible for a non-specialist to grasp GRADE basics very quickly.
目的
推荐分级评估、制定与评价（GRADE）系统可被认为是最常用于评估系统评价和指南中纳入研究的方法。为了使用 GRADE 系统或在阅读综述时知道如何解释它，需要阅读几篇文章并参加研讨会。此外，标准医学教科书中并未涵盖 GRADE 系统。在这里，我们使用示例简明扼要地解释 GRADE 系统，以便学生和其他研究人员能够理解它。
背景
为了使用或解释 GRADE 系统，目前需要阅读几篇文章并参加研讨会。此外，标准医学教科书中并未涵盖 GRADE 系统。
方法
我们阅读、综合和消化了 GRADE 出版物，并在需要时联系了 GRADE 贡献者进行解释。我们以一种普通医学受众能够理解的简洁方式组成了系统的消化版本。
结果
我们能够在不到 1500 字的篇幅内清楚而完整地解释 GRADE 的基础知识。
结论
虽然高级批判性评估需要判断、培训和实践，但非专家也可以很快掌握 GRADE 基础知识。
