#  Viewing Changes to a Study 

 



When a study changes based on reviewer requests, you can click view study in the workspace to re-review the revised submission, or to look only at what has changed, you can:

- View the response submitted for a particular request
- View the differences between two versions of a study

**View Differences**

6\. Exit the View Differences screen by clicking **Close** on the right.

Sort**TIP**

If the study team updated the documents, they may contain tracked changes. You can use the review features in Word to toggle between showing the original and final versions of the document. When the IRB approves the documents, all tracked changes will be accepted and comments removed in the final versions.





**Document Compare**

If a revised document is uploaded as a revision, each version of the document is stored on the document history. For Microsoft Office documents which support tracked-changes (such as Word), Two versions may be selected to generate a tracked version for review.

**To access document history and create a tracked-changes version:**  
1\. From My Inbox, click the name of the study to open it.  
2\. Click **Printer Version** on the left or the **Documents** tab on the center of the page  
3\. Navigate to the document   
4\. Click the **History** link

5\. In the pop up, choose two versions to compare  
6\. Click the **Compare** button

   ![View of document compare function pop up](/sites/g/files/omnuum886/files/styles/hwp_1_1__720x720_scale/public/estr/files/document_compare.png?itok=lKQ7UDbT) 

 

  
  
7\. A pop up will appear to save the tracked version to your compute  
8\. Save the document and view the changes

**Snapshots**

A snapshot is a record of a submission at a particular point in history. The snapshot includes all SmartForm fields, along with attachments. Snapshots can be used to see what was previously reviewed or approved.  
  
Snapshots (noted with camera icon here) are **taken at specific points during the review** of each submission:

Snapshots are taken at minor (ex. 0.1, 0.2, 0.3…) and major increments (ex. 1.0, 2.0, 3.0…). When viewing **snapshots on the tab in a workspace, it can be read:**

**Other Notes about Snapshots**

- Snapshots are also added on the main study workspace each time the study is approved via a Modification, and will appear as a major increment in the Approved state.
- Snapshots are not taken when a continuing review is approved because nothing changes about the SmartForm when a continuing review is approved.
- When ESTR was upgraded in October 2015, pre- and post- migration snapshots for existing submissions were captured to verify data elements affected by data migration. These snapshots were recorded for tracking purposes and do not represent a change in the study.
- When a printable packet is created, an additional link will appear here. It will be labeled “Smartform Pages as of…” This snapshot is recorded for tracking purposes and does not represent a change in the study.
