Cochrane Library

The Cochrane Library is a collection of databases that contain high-quality, independent evidence to inform healthcare decision-making. Cochrane reviews represent the highest level of evidence on which to base clinical treatment decisions. In addition to Cochrane reviews, The Cochrane Library provides other sources of reliable information: other systematic review abstracts, technology assessments, economic evaluations, and individual clinical trials – all the current evidence in one single environment.
 
Search Tips

Boolean operators AND, OR, and NOT can be selected from the pulldown selection boxes or entered directly within the search text boxes. Use parentheses to separate components when entering complex search directly in text box with mixed Boolean operators.

Example: (colchicine AND liver) AND (fibrosis OR cirrhosis)

 

Truncation: Search for accented characters (within all fields except Author) by using both the accented and unaccented versions of a term or by using wildcard (multiple: *) or (single: ?) characters.

Example: meniere* or ménière*

Example: m?ni?re*

Both examples match Meniere's or Ménière's
