چکیده
In fact, if an asterisk is added to the end of a phrase, truncation is performed. No double quotes are required around the phrase, as the asterisk acts as a phrase marker as well as truncation. The PubMed searches in the supplementary material duplicate the search string used in the article. Sets 3 and 9 utilize the phrase truncation feature (figure 1). The number of results is the same for the terms using this feature as it is for each individual variation of the term using a Boolean “OR.”
