Articles that provide evidence-based recommendations for clinical research and practice, or public health policy. Guidelines should be developed through a rigorous process and provide clear, actionable advice.

-Abstract: Non-structured abstracts are acceptable

-Contents： The guidelines should include a brief overview, evidence-based recommendations graded by strength, evidence summaries (possibly supplemented with tables/figures), an analysis of implications, benefits, and limitations, and practical implementation advice.

-Length: While the length of guidelines can vary, they should be concise and focused. Striking a balance between comprehensiveness and brevity ensures user-friendliness without missing essential details.
