在写文章的时候，可以发现，基本上所有的文章末尾都会有Data Availability Statement (Data Access Statement)。在这里，一般包括文中出现的数据可以在哪里获取，怎样获取，必要的时候还会附上获取链接。

我常用的几种写法：

开放的：

1 . Data openly available in a public repository. (完全开放，可以自由下载)

The data that support the findings of this study are openly available in [repository name] at [URL].

2. Data available within the article or its supplementary materials. （半开放，可以找到）

The authors confirm that the data supporting the findings of this study are available within the article [and/or] its supplementary materials.

3. Data available on request from the authors. （一般开放，可以要到）

The data that support the findings of this study are available from the corresponding author, [author initials], upon reasonable request.

不开放的：

4. Data not available due to [ethical/legal/commercial] restrictions. （不提供）

Due to the nature of this research, participants of this study did not agree for their data to be shared publicly, so supporting data is not available.

相对而言，我更喜欢1那样的文章，这样可以嫖一把数据看看；但事实上，3这种情况的略多，所以我觉得3基本上等同4。
