Bulk PDF Upload feature


The bulk PDF Import tool enables you to upload all of your full text review PDFs at once.

To access the feature you might need to upgrade your account (given the additional user support, this feature isn’t available on free trial reviews).

Once the feature is enabled, upload your PDFs in bulk from the ‘Import PDFs’ page in the Import studies tool, according to these simple steps.

Improved display of studified references


At Covidence we’ve created the term ‘studified’ to refer to references that have been grouped together because they are referring to the same study.

We understand how important your time is, so if you’ve studified your records externally we’ll make sure these are maintained. Let’s cheers to fewer references to screen!

This happens specifically if you’ve studified records using the ‘NS’ field in your RIS file.

If you import a studified reference, it will automatically be grouped together with its associated references, depending on where they already are in your review. In other words, the reference will be moved forward in your review without the need for you to screen it again.

We’ve also made some subtle changes to the way in which studified records will now be displayed. As you can see below, actions such as undoing votes, viewing history and viewing notes are all on a per study basis, as opposed to per reference.

Custom data extraction fields for Identification, Methods and Population sections


Under the parts of the data extraction form for Identification, Methods and Population you can now add any number of new fields!

You can read more about using these at our Knowledge Base.

Support custom Study Designs


You can now input absolutely any type of study design in your data extraction forms!

Under the Methods section, either choose one of our pre-programmed options, or opt for “other” and type a design of your choice.

Collect overall and per-arm baseline characteristics


Previously Covidence allowed you to collect baseline characteristics data by intervention arm or overall. We had heard from some of our users that it would be more useful to be able to collect data both by intervention arm and overall so we’ve made the change!

Custom Effect Measures


If the results in your study are in a format not represented by one of our standard options, you can now create new custom effect measures! These can be in any format and have any number of variables.

Just so you know, these won’t currently export to RevMan, but they definitely will export to Excel/CSV.

You can read all about this new feature at our Knowledge Base.

Filtering and exporting of tags


Tags added to your references in Covidence now export to Excel.

Also, filtering by tag is now available in all reference list screens, where previously this was only available in screening and full text review.

We've noticed many users use tags to indicate references they'd like to use later on for discussion or for a different review. Previously, if references had a tag but were then excluded from your review, there was no simple way to retrieve them.

With these updates, there are two ways in which you can track down these references:

  1. By filtering a specific list in Covidence. Filtering was previously available in screening and full text review only, and is now available in all stages!

  2. By exporting your references to Excel. Tags will now appear in a separate column, making them easy to sort, filter, or label.

Another common use we've seen is labelling references with a study design tag to indicate which data extraction form should be used. Now that you can filter by tag in the extraction screen, your review team does not have to go searching for certain studies — they can simply filter by tag!

Add notes to a study


We're happy to announce that you can now add notes to a study at any stage in the review process. Notes are also included in any reference list export and in a RevMan export.

New Risk Of Bias feature


We're pleased to have released a completely new Risk of Bias tool to help you with your quality assessment. The new tool allows you to customize your domains and also supports outcome based risk of bias.

See our Knowledge base for more info.

Updated data extraction form UI


We've combined the PDF and the form into a single view which we think will save you time completing your data extraction.
