# Uploading Review Data

It is possible to upload literature search results exported from an external database:

* Use this option to perform literature screening using data from proprietary third party data sources
* All of MLM-AI's screening, auditing and AI-based automation features can be used on uploaded results

Currently, it is possible to upload results exported from these systems:

<table><thead><tr><th width="201.33333333333331">Source System</th><th>Expected Format from Source System</th></tr></thead><tbody><tr><td><strong>PubMed</strong></td><td>PubMed's <a href="https://pubmed.ncbi.nlm.nih.gov/help/#citation-management-software">nbib reference format</a>. </td></tr><tr><td><strong>PubMed</strong></td><td>PubMed email alerts in nbib reference format as <code>eml</code> email file</td></tr><tr><td><strong>Embase</strong></td><td>RIS citation management export, or <code>csv</code></td></tr><tr><td><strong>EBSCO</strong></td><td>RIS citation management export</td></tr><tr><td><strong>Adis</strong></td><td><code>csv</code> export</td></tr><tr><td><strong>ProQuest/Dialog</strong></td><td>Excel export</td></tr><tr><td><strong>EMA (Excel)</strong></td><td>Eudravigilance EMA MLM files for consolidation</td></tr></tbody></table>

Depending on the source of exported results, uploads could be automated. Refer to [Integrations](/application/integrations.md) to find out how.

## Uploading Multiple Files

For convenience, uploading files can be done in bulk saving time in routine weekly uploads of search results.

* Select **Upload** as the review type
* You can drag files directly from your desktop anywhere into the area marked as "Drag and Drop files here"

* Once files are uploaded, configure them by mapping to the Monitor, file type and start-end date of search results

## Applying Default Values

Configuring uploads can be done one file at a time, or you can select multiple files and apply the same setting to all.

* Example: if the source data for your files is always the same you can select one default value and apply to all
* Select what files to apply defaults, then choose "Edit Selections"

* In the Dialog, select default values for File format, Dates and Monitor (leave empty the fields you do not need default values for)
* Click "Apply"
* Complete filling any remaining fields as needed

## Verification

Once entering parameters is complete, files can be Verified by clicking the "**Verify**" button. This will pre-process files to ensure the file format is correct and now rows are corrupted.

* If successful, file status will change from "**To Verify**" to a green indicator of the number of records to be processed
* Once verification is complete, the "**Upload**" button will become enabled and files can be uploaded

## What Happens after the Upload

Uploaded files will generate new [Reviews](/application/reviews.md). They will be visible in the "Processing" tab in the [Review Summary](/application/reviews.md) page, and will become available (ie. move to the "In-Progress" tab) once processing finishes.

From this point, results can then be normally screened, like any other Review produced by MLM-AI.

### Unique Records During Upload

* Uploaded records are identified by their **unique ID from the source** when uploaded
* This ensures only a single record exists for the corresponding unique record from the source and facilitates duplicate detection
* Therefore, subsequent uploads of citations with an existing unique ID do not create new records in the MLM-AI database

During the verification step, users can verify if repeated IDs are present in their upload file and if they will be discarded. Example:

<div align="left"><figure><img src="/files/5wdj5DMnCf9gmkEegZ8w" alt=""><figcaption></figcaption></figure></div>

Clicking the badge shows further details of specific IDs detected as already existing.

Article de-duplication is also available for uploaded data. Learn more in the [Duplicate Detection](/topics/duplicate-detection.md) page.

## Supporting Guides for Exporting from External Databases

* For PubMed, follow the steps for [exporting into a citation management format](https://pubmed.ncbi.nlm.nih.gov/help/#citation-management-software)
* For Embase, refer to [this guide](http://supportcontent.elsevier.com/Support%20Hub/Embase/Files%20&%20Attachements/5540-Embase%20E105%20-%20Saving%20Searches%20and%20Exporting%20Results%20-%20June%202015.pdf) for steps on how to search results
