大数据背景下观察性研究中对照选择的方法学进展

Methodological progress in selection of control in observation study in the context of big data

对照选择作为流行病学研究设计的核心,伴随健康医疗大数据研究的日益增多,其策略在不断丰富和完善,不同策略潜在影响的估计方法也在不断提出和推广。中国流行病学工作者亟需紧跟国际对照选择相关的方法学趋势,发现并解决方法学本土化问题,以便更好地服务于健康医疗大数据的开发。

Control selection is the core of epidemiological study. With the increase of studies based on big data in healthcare, the strategies for control selection were continued to enrich and improve. The methodologies to estimate the potential impact of each control selection strategies were also proposed. To facilitate the utilization of big data in healthcare, the Chinese epidemiologist should keep in step with the international trend in the field of control selection, and should find ways to localize the strategies for control selection.
