PubMed users can now go straight from the trial to the systematic review that cites it. This new feature, called a portlet, appears on the right hand side of the abstract display page. For example, the study, “Breast cancer after use of estrogen plus progestin in postmenopausal women,” was cited by five systematic reviews. Links to these systematic reviews are available in the portlet.
If the portlet is not showing, it does not necessarily mean that there are no systematic reviews that include the trial.
This new feature helps users follow research through time. Look for this new portlet the next time you are using PubMed.
