方法论 / Methodology

证据优先,不夸大结论

我们把事实、推断、编辑判断和待核验问题分开呈现,让读者看到结论,也看见结论的边界。

We separate facts, inferences, editorial judgment, and open questions—so readers can see both a conclusion and its limits.

来源优先级 / Source hierarchy

  1. 系统综述、Meta 分析与高质量人体试验
  2. 权威公共卫生机构与专业指南
  3. 同行评议观察性研究与机制研究
  4. 动物研究,仅用于解释机制,不直接升级成人体处方
  5. 趋势平台只用于选题信号,不用于支持科学结论

证据等级 / Evidence grades

A

高共识或多项可靠人体证据

Strong evidence or broad consensus

B

中等证据,结论需保留边界

Moderate evidence with clear limits

D

主要来自动物或机制研究

Mainly animal or mechanistic evidence

U

证据不足,不作确定结论

Insufficient evidence for a firm conclusion

编辑与修订 / Editing and corrections

核心结论至少需要可靠来源支持。中英文必须保持科学事实一致;标题不得超过正文证据。若新研究改变结论,我们会更新最近修订日期并保留同一永久链接。

Core claims require reliable sources. Chinese and English versions must preserve the same facts, and headlines may never outrun the evidence. Material updates keep the same permanent URL and receive a new revision date.
