  • Use the ( and ) brackets to group terms together

  • You can end a term with * to match similar words.

    • Ex: pregnan* will match pregnant, pregnancy, pregnancies...

Examples:

Goal
Example Query

Search for any query terms with an OR query

acetaminophen OR paracetamol OR panadol

Search for multi-word terms with quotes

"liver damage" OR "liver toxicity"

Search for keywords AND the presence of one or more events

(acetaminophen OR paracetamol OR panadol) AND ("liver damage" OR "liver toxicity" OR "liver failure")

Auto-Expansion of Medication Names

Selecting a medication keyword with the mouse will display the "Expand" icon. Clicking on it will bring up a list of synonyms for selection. These will be included back in the query as an OR section:

Select Dates and Source Databases

Use the Start/End dates to specify the date range to search. This will retrieve articles by publication or entry date within the date range.

Alternatively use the range buttons to quickly select last week, month or year.

Each data source available can be toggled using the selectors.

Advanced Query Editor

More complex searches can be edited in a larger view by clicking the advanced button

This view also performs syntax checking as you type.

Adverse Terms and Query Strings

Where possible it is recommended to use the AI tags in place of explicit lists of adverse terms.

Query String Limits

Queries are limited to 1,000 results. When this limit is reached you will be informed with the warning below. Try reducing results with a shorter date range or a less broad query.

Comparison Mode

When designing a query string it is important to understand the impact of adding and removing query terms. Use the Compare tab to perform analysis of results between two searches.

The example below evaluates differences between an open query and a more restrictive one (with AND clause). Click on the image to expand:

Analyze Mode

Finally, it is also important to estimate the expected volume of hits from the query string to help users understand and plan for screening effort, in particular for periodic searches.

The Analyze tab automates this analysis and presents estimated hits obtained from historical periods.

The example below illustrates weekly volumes for a sample search over a 2 month period.

Create Monitors from Searches

Clicking the "pill" button will direct to the Monitor configuration page, where additional monitor details can be entered.

In MLM-AI, adverse events are captured by . The AI tags are designed to replace long lists of adverse "keywords" such as adverse event, adverse reaction, etc.
