            <strong>Open Evidence</strong> 是一个专为医疗卫生专业人士设计的、基于人工智能的医学信息检索与决策支持平台。与通用的 AI 模型（如 ChatGPT）不同，Open Evidence 采用了先进的<strong>检索增强生成 (Retrieval-Augmented Generation, RAG)</strong> 技术，确保其生成的每一个回答都严格基于高质量的、同行评审的医学文献（如 PubMed, NCCN 指南, 权威医学期刊）。Open Evidence 的核心价值在于<strong>“无幻觉” (Hallucination-free)</strong> 和<strong>“可溯源” (Verifiable)</strong>——它会在回答的每一句话后标注具体的引文出处，点击即可跳转至原始论文，从而让医生和研究者能够快速、放心地获取准确的循证医学证据。

    <p style="margin: 15px 0; text-align: justify;">
        Open Evidence 解决了通用大模型在医学领域最大的痛点——<strong>一本正经地胡说八道 (Hallucination)</strong>。其工作流程如下：
        
    </p>

    <ul style="padding-left: 25px; color: #334155;">
        <li style="margin-bottom: 12px;"><strong>实时检索 (Retrieval)：</strong> 当用户提问（例如“奥希替尼在一线非小细胞肺癌的最新生存数据”）时，系统首先在千万级的医学文献库中进行高精度搜索，而非直接让 AI 凭记忆生成。</li>
        <li style="margin-bottom: 12px;"><strong>证据筛选 (Grounding)：</strong> 系统筛选出最相关、最权威的片段（如来自《NEJM》或《Lancet》的摘要）。</li>
        <li style="margin-bottom: 12px;"><strong>溯源生成 (Citing)：</strong> 大模型基于这些筛选出的片段生成回答，并强制要求在句尾加上数字角标，链接回原始文献。如果找不到证据，系统会倾向于回答“未知”而非编造。</li>
    </ul>

    <h2 style="background: #f1f5f9; color: #0f172a; padding: 10px 18px; border-radius: 0 6px 6px 0; font-size: 1.25em; margin-top: 40px; border-left: 6px solid #0f172a; font-weight: bold;">工具对比：新旧范式之争</h2>

        <p style="margin: 0; text-align: justify; font-size: 0.95em; color: #334155;">
            <strong>定位差异：</strong> <strong>UpToDate</strong> 是由专家人工撰写的静态“电子书”，权威但更新慢；<strong>ChatGPT</strong> 是通才，但这容易编造数据；<strong>Open Evidence</strong> 是“阅读速度极快的 AI 助手”，兼顾了时效性与真实性。
