Truncation is a search method in which symbols are used in place of letters or words to help you broaden your search. It is a recommended practice when building the queries to be used in systematic reviews.

However, it is important to keep in mind that using a truncation sign at the end of a word will either replace or add characters to the truncated word. Depending on the database, a truncation sign can add none, one or more characters. Common truncation signs are: asterisk (*) and question mark (?). Make sure the truncation sign is correctly placed as the truncation process is database specific and unique problems may arise working with each database. Consultation with a librarian who is knowledgeable in building the queries may help.

Like answered above, make sure how each database behaves with the asterisk (*). For PubMed, it works like magic.

Best of luck!
