数据可用性声明（Data Availability Statement）是指在科研文章中声明研究数据的可获取性及获取方式的说明。数据是支撑科研结论的关键，明确的可用性声明直接影响到研究的可重复性和透明度。

投稿时，大多数SCI期刊会要求作者提供原始数据，以及撰写涉及文章数据的可用性声明（一般写在文章末尾参考文献之前）。

（投稿系统中关于数据可用性声明的截图）

数据可用性声明需要作者回答：

1. 数据在哪里？数据是存储在公开数据库、实验室服务器，还是随论文提供？作者需要简单交代清楚哦。

2. 谁可以用？数据是公开共享的，还是仅限授权使用？有些数据涉及隐私，需获得许可才可使用。

3. 如何引用？如果数据库或数据集有特定的引用格式，应在声明中说明，以便规范引用。

1 数据可用性声明模板

不同领域和情况的数据可用性声明可能有所不同，建议作者查看目标期刊的作者指南（Author Guidelines/ Guide for authors），以确保符合要求。以下是一些常见模板，供大家参考。

更多具体领域的模板供参考：

1） 生命科学与临床医学领域

① 存储库中公开提供的数据：

模板1

PRO-Seq data were deposited into the Gene Expression Omnibus database under accession number GSE85337 and are available at the following URL:https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE85337.

模板2
