Perform AND and OR searches

By default, VigiLyze uses OR logic within a specific category, for example drugs or reactions. Between different categories AND logic is used.

An OR search provides reports matching any of the selected terms.

Example

Drug A OR Drug B

The search will retrieve all cases that contain Drug A, Drug B, or both, providing a broader set of results that includes reports where either search term is present.

Creating an AND search

To search reports that contain multiple terms:

1. Add the search terms.

2. Drag one term onto another.

3. Release the mouse button.

The search changes to AND logic.

Example

In the example above, we start with an OR search for Tamoxifen and Tranexamic acid.

By draging and dropping the Tranexamic acid onto Tamoxifen it becomes and AND search.

The search will retrieve all cases in which both Tamoxifen and Tranexamic acid are reported together in a same report. Applying both search terms narrows the results to cases containing both medicines.

The same approach can be used for reaction terms.

Returning to OR search

1. Drag one term away from the other.

2. Release the mouse button

The search will return to OR search

VigiLyze does not support NOT searches or exclusion criteria.
