You can search within all trials that their registration has been completed in IRCT. This could be done in two ways:
Basic search: You can enter a complete word from anywhere in the trial protocol. You can also type complex search terms here.
Advanced search: In advanced search you can use a tool that helps build your complex search term using “AND”, “OR”, “NOT” and applying it on any particular protocol item registered in IRCT. The result of previous queries has also been shown and could be re-used in the new search term. Please see the example below and carefully study the search term that has resulted from the selections.
