This randomized, parallel-group, assessor-blinded educational study will evaluate whether one session of AI-assisted structured guidance improves the quality of narrative literature reviews written by medical postgraduate students. A total of 102 students enrolled in an academic writing course will be randomly assigned to either an AI-assisted structured guidance group or a free AI use group. Both groups may use AI tools under academic integrity requirements and will complete a narrative literature review according to the same course requirements. The guidance group will receive one structured guidance session approximately two weeks before final submission. The session will be based on the six dimensions of the Scale for the Assessment of Narrative Review Articles (SANRA). The primary outcome is the final SANRA total score of the submitted narrative literature review.

Generative artificial intelligence is increasingly used by medical students and postgraduate trainees for literature searching, summarization, outlining, and academic writing. However, free use of AI may be associated with inaccurate information, unsupported statements, fabricated references, and inadequate academic judgment. This study is designed to evaluate whether structured guidance can improve the quality and academic integrity of AI-assisted narrative review writing.

Participants will be medical postgraduate students enrolled in an academic writing course. After informed consent and baseline data collection, participants will be randomized in a 1:1 ratio to an AI-assisted structured guidance group or a free AI use group. Both groups will complete a narrative literature review of approximately 2,000 Chinese characters according to the same course requirements and may use AI tools under academic integrity requirements.

Participants in the AI-assisted structured guidance group will receive one structured guidance session approximately two weeks before final submission. The session will be based on the six SANRA dimensions: explanation of the importance of the article, statement of aims or questions, description of the literature search, reference support for key statements, scientific reasoning, and appropriate presentation of data and content. The instructor will provide directional and methodological feedback but will not directly write or edit the students' text line by line. Participants in the free AI use group will complete the review according to the same course requirements without the structured guidance session.

After submission, all narrative reviews will be anonymized and assessed by independent outcome assessors blinded to group allocation. The primary outcome is the final SANRA total score. Secondary outcomes include SANRA item scores, multiple-source academic writing self-efficacy, and reference authenticity error rate.

Inclusion Criteria:

1. Master's students enrolled in the Academic Standards and Thesis Writing course.
2. Willing to participate in this study, able to understand the study procedures and randomization arrangement, and able to provide written informed consent.
3. Able to complete literature searching, use AI tools, and complete online questionnaires.

Exclusion Criteria:

1. Students who have confirmed withdrawal from the course, suspension of study, long-term leave, or other known objective reasons that prevent participation in subsequent major teaching activities and study procedures.
2. Students who have participated in pilot testing, intervention material development, assessment training, or data processing related to this study.

Individual participant data will not be shared because the study involves students' coursework, questionnaires, AI use declarations, and writing-related educational data. These data may contain potentially identifiable information even after de-identification. Only aggregated results will be reported in publications or academic presentations.

Outcome assessors will be blinded to group allocation. Final narrative literature reviews will be anonymized before assessment, with names, student identifiers, group assignment, guidance records, and AI use declarations removed. Independent assessors will evaluate the anonymized reviews using the SANRA scale.
