How to create a data extraction form

Before you can create a data extraction form you need to add sources to your review, import studies, select them and create a quality assessment checklist.

Data extraction forms are useful to extract the data from the selected studies, as you read them, so you can put all the results together and analyze afterwards.

You can create a data extraction form for your review at Review » Planning Tab » Data Extraction Form.

A data extraction form is basically composed by a collection of fields, each field has a name and a type property, and if this field is a selectable field, it may have some pre-defined values. All the field types are listed below:

Field type	Values
Boolean Field	True or False
String Field	Text
Float Field	e.g. 10.4 or 176.23
Integer Field	e.g. 1 or 40
Date Field	Format mm/dd/yyyy
Select One Field	List of pre-defined items to select one value (combo box, dropdown list)
Select Many Field	List of pre-defined items to select many values (collection of checkboxes)

You can create forms with unlimited number of fields. For the sake of simplicity you can create all your form fields as string, but the field types can help you keep the integrity of the data, as Parsifal will validate them for you as you fill the form.
