摘要:

目的:了解我国医疗器械技术审评报告中临床试验设计与统计分析要素的公开情况。方法:通过提取国家药品监督管理局官网的医疗器械公开审评报告信息,将2023全年度的公开技术审评报告作为研究对象,提取相关信息并进行汇总分析。结果:本研究共纳入了60项临床试验,涉及医疗器械分类条目中全部类型(22个)中的17个,试验设计与分析要素的报告呈现多样性。在临床评价概述中,只有样本量信息被全部明确提及,但有51.5%的临床试验未明确说明是否应用盲法设计,有41.7%的试验未明确说明主要指标结果所基于的统计分析人群。结论:国内医疗器械审评报告反映了上市前临床试验现状,但临床评价与试验设计方法学信息公开仍存在透明度不足的情况。建议规范临床试验设计与统计分析要素公开标准并建立分类机制,提升方法学要素透明度,助力临床试验科学化发展。

Abstract:

Objective: To know the reporting status of clinical trial design and statistical analysis elements in the technical evaluation report of medical devices in China.Methods: Public technical review reports of medical devices published on the National Medical Products Administration NMPA website in 2023 were selected as research subjects. Relevant information will be extracted and summarized for analysis.Results: This study included a total of 60 clinical trials involving 17 out of 22 device classification categories. The reporting of trial design and analysis elements showed diversity. In the overview of clinical evaluation only sample size information is explicitly mentioned but 51.5% of clinical trials did not specify whether blinding design was used and 41.7% of trials did not specify the statistical analysis set on which the primary endpoint were based.Conclusion: Current medical device review reports reflect the status of premarket clinical trials in China yet transparency gaps persist in disclosing methodological elements of clinical evaluation and trial design. Standardizing disclosure criteria and establishing a classified disclosure mechanism are recommended to enhance methodological transparency and promote scientific advancement in clinical trials.
