Clinical practice guidelines serve as a critical tool for bridging evidence and clinical practice, with the quality and clarity of their recommendations directly influencing implementation outcomes. Based on the classification framework of guideline actionable statements proposed by Lotfi, this article systematically interprets the definitions, characteristics, and applicable conditions of six types of guideline statements: formal recommendations, research only recommendations, good practice statements, implementation considerations, tools and tips, remarks, and informal recommendations. A comparative analysis with mainstream international guideline development manuals is also provided. The article emphasizes the importance of standardizing statement classification to enhance the methodological quality and implement ability of guidelines, offering practical insights for both guideline developers and users.
