The clinical trial aimes to evaluate multiple large language models in respiratory disease consultations by comparing their performance to that of human doctors across three major medical consultation scenarios.
The main question aims to answer are:
In three clinical scenarios including the online query section, the disease diagnosis section and the medical explanation section, research assistants or volunteers will be asked to cross-question all LLMs or real doctors using predefined online questions and their own issues. After each questioning session, a short washout period is implemented to eliminate potential biases.

| Diagnosis by three human doctors | Diagnostic Test | This intervention involves answering patient inquiries by different human doctors. Each patient is randomly assigned by the system to three doctors from different provinces in China selected from the database of doctors. The doctors all come from multiple online consultation platforms in China, and their diagnostic qualifications and medical licenses have undergone strict verification. |
| Measure | Description | Time Frame |
|---|---|---|
| Expert indicators-Accuracy | Based on the doctors' responses to patients' issues, a 5-point scale will be used for scoring by an expert panel: 5- The responses are completely accurate, addressing all of the patient's questions or diagnosing by identifying the key points of the patient's complaint. 4- The responses are mostly accurate, generally addressing the patient's questions or diagnosing by identifying the key points of the patient's complaint. 3- The responses are moderately accurate, addressing the patient's questions or diagnosing by identifying the key points of the patient's complaint. 2- The responses are rarely accurate, barely addressing the patient's questions or diagnosing by identifying the key points of the patient's complaint. 1- The responses are very inaccurate, not addressing the patient's questions or diagnosing by identifying the key points of the patient's complaint at all. | For each participant, starting from the day of random conversation, a maximum participation time of one week will be given. As for subjective expert indicators, the evaluation will be conducted within two months. |
| Expert indicators-Comprehensiveness | Based on the doctors' responses to patients' issues, a 5-point scale will be used for scoring by an expert panel: 5-The responses are highly comprehensive, addressing various aspects of potential diseases corresponding to the patient's symptoms, providing detailed advice, and offering its own extended interpretations. 4-The responses are mostly comprehensive, covering most aspects of potential common diseases related to the patient's symptoms, and providing fairly detailed advice. 3-The responses are moderately comprehensive, addressing some aspects of potential common diseases related to the patient's symptoms, and offering basic advice. 2-The responses are rarely comprehensive, failing to consider various aspects of potential common diseases related to the patient's symptoms, and providing very limited advice. 1-The responses are not comprehensive at all, overlooking most potential diseases related to the patient's symptoms, and failing to provide any advice. | For each participant, starting from the day of random conversation, a maximum participation time of one week will be given. As for subjective expert indicators, the evaluation will be conducted within two months. |
| Expert indicators-Correctness |
| Measure | Description | Time Frame |
|---|---|---|
| Regular indicators-Total number of questions | The number of follow-up questions asked by the LLM or real doctor to the patient after providing basic answers in a complete conversation. | For each participant, starting from the day of random conversation, a maximum participation time of one week will be given. After the completion of the dialogues, the system will automatically summarize all objective indicators and dialogue information. |
