读者从 PubMed 数据库导出以下文章的书目，并选择以 APA 格式呈现，但不确定红色数字符串与”Advance online publication”代表的意义。
Li, Y. C., Lin, K. C., Chen, C. L., Yao, G., Chang, Y. J., Lee, Y. Y., Liu, C. T., & Chen, W. S. (2023). Three ways to improve arm function in the chronic phase after stroke by robotic priming combined with mirror therapy, arm training and movement-oriented therapy. Archives of physical medicine and rehabilitation, S0003-9993(23)00150-8. Advance online publication. https://doi.org/10.1016/j.apmr.2023.02.015
我们从期刊出版社 Elsevier 官网及其 ScienceDirect 数据库确认，这是一篇待刊论文（Articles in press），已经被接受与同侪审查，已经有doi，但是尚未编入特定卷期与页码。https://www.sciencedirect.com/journal/archives-of-physical-medicine-and-rehabilitation/articles-in-press
仔细观察这篇文章在ScienceDirect数据库所属的网址，有包含PubMed数据库书目显示的数字符串，推测可能是出版社给这篇文章的某种编码。https://www.sciencedirect.com/science/article/pii/S0003999323001508
至于如何引用在线预行出版论文、待刊论文呢？以 APA 第7版为例，可参考国外大学与APA官方网站的指引。如下图所示，可于期刊名后面标示 Advance online publication，或者在作者名后面标示 (in press)。
1. The University of Queensland Library — APA 7th referencing style：
除了列出文内引用与参考书目的实例，也提供书目管理软件EndNote建档字段的建议，可于 Article Number 字段输入 Advance online publication；可于 Year 字段输入 in press。
