Screening

In Screening, you select which studies to include in your nest and which should be excluded (with reasons).

Steps to Screen a Nest:

1. Configure Screening

Before screening individual studies, you must Configure Screening. To Configure exclusion reasons, list all reasons that a record would be excluded from your nest.

2. Select Screening Mode

There are several Screening Modes that you can select to alter the flow of records through your nest. Each option can be toggled on the Admin page for your nest:

Screening Modes:

The best practice is to choose a Screening Mode before you begin Screening. While you can switch between Screening Modes at any point, and final Inclusion/Exclusion decisions can be carried over, switching modes after beginning Screening can result in lost data.

2a. Select Screening Queue Order

By default, studies shown in the screening queue will be ordered by Ref ID. If you wish, you can change this to randomized or by likelihood of inclusion (if a screening model was trained).

3. Configure Your Keywords

To aid users in screening, you can configure keywords either in the Configure Screening page or on the Abstract view of any study in your nest. These User Keywords will be underlined in all abstracts.

These are different from the P, I, and O highlighting in that the highlighting is automatically generated by our RoboPICO software based on the abstract's contents, while Your Keywords are custom-added as described here.

4a. Include and Exclude Records

The core activity of Screening is Including and Excluding records. In this process, you review the abstracts of records and exclude any that meet your Exclusion Reasons. For any article that is includable (as in, no Exclusion Reason applies), select “Include” and (optionally) upload the full text. There is also an option to “unscreen” a study. You can do this on individual studies or across many studies in a bulk action.

Uploading Full Texts

Generally, you should complete Full Text PDF Upload for any record that you Include, so that it is available to Tag during the next stage. The exception: if you set up the Two-Pass Screening Mode (see above), you should upload full texts for all studies that are Advanced to Full Text Review.

There are several options for Full Text Upload:

See instructions for bulk upload here.

See instructions for individual FT upload here.

While screening, it isn't unusual to find the same data reported across multiple papers, and you will most likely include both the primary papers and all the secondary analyses. For the non-primary papers with data from the same trial, you can mark them as related reports to keep track of them and to have the PRISMA adjusted to reflect the difference in the number of studies versus the number of reports.

5. When are you finished Screening?

You are finished Screening when all records in your nest are either Included or Excluded, as indicated by the Screening progress bar accessible within the module in the top right. At this point, you should move on to Tagging and Meta-Analytical Extraction (previously named Extraction) (optional) for the included records!
