<a name="note">[</a><em>Editor's note: These changes were implemented in PubMed on March 8, 2017.</em>]
</p>
<p>
The National Library of Medicine (NLM) is pleased to announce four upcoming enhancements to PubMed.
</p>
<h2>1. Conflict of Interest Statements (COIS)</h2>
<p>
PubMed will include conflict of interest statements below the abstract when these statements are supplied by the publisher (see <a href="#fig1">Figure 1</a>).
</p>
<a name="fig1"></a>
<div class="figure"><br />
<img src="/pubs/techbull/ma17/graphics/pm_update_fig1.png" alt="Conflict of interest statement expanded to show details" title="Conflict of interest statement expanded to show details" /><br />
<strong>Figure 1. Conflict of interest statement expanded to show details.</strong>
</div>
<ul>
<li>The corresponding tag for the MEDLINE display is COI.</li>
<li>Search <strong>hascois</strong> in PubMed to retrieve all citations that contain conflict of interest statements.</li>
<li>Use the field tag <strong>[cois]</strong> to restrict your search to this field, for example: <strong>merck[cois]</strong></li>
</ul>
<h2>2. Editorial Expressions of Concern</h2>
<p>NLM is adding editorial expressions of concern as a new pair of linking elements in the Comments/Corrections suite in PubMed. Expressions of concern, previously handled as comments, will be labeled explicitly in the abstract display (see <a href="#fig2">Figure 2</a>).
</p>
<a name="fig2"></a>
<div class="figure"><br />
<img src="/pubs/techbull/ma17/graphics/pm_update_fig2.png" alt="Labels for the new Expression of Concern linking elements" title="Labels for the new Expression of Concern linking elements" /><br />
<strong>Figure 2. Labels for the new Expression of Concern linking elements.</strong>
</div>
<ul>
<li>The corresponding tags for the MEDLINE display are:
<ul>
<li>ECF - Expression of concern for will appear on the citation for the Expression of Concern.</li>
<li>ECI - Expression of concern in will appear on the citation for the original article.</li>
</ul>
</li>
<li>Use the search <strong>hasexpressionofconcernfor</strong> to retrieve the citations that contain editorial expressions of concern.</li>
<li>Use the search <strong>hasexpressionofconcernin</strong> for the citations to the original articles.</li>
</ul>
<h2>3. Results Display</h2>
<p>
The "Per page" menu, which allows users to customize the number of items that appear on the results screen, will appear at the top of the results list (see <a href="#fig3">Figure 3</a>).
</p>
<a name="fig3"></a>
<div class="figure"><br />
<img src="/pubs/techbull/ma17/graphics/pm_update_fig3.png" alt="Per page menu at the top of the results display" title="Per page menu at the top of the results display" /><br />
<strong>Figure 3. "Per page" menu at the top of the results display.</strong>
</div>
<h2>4. Status Tag</h2>
<p>
The status tag [PubMed indexed for MEDLINE] will be replaced with the tag [Indexed for MEDLINE] (see <a href="#fig4">Figure 4</a>).
</p>
<a name="fig4"></a>
<div class="figure"><br />
<img src="/pubs/techbull/ma17/graphics/pm_update_fig4.png" alt="New [Indexed for MEDLINE] status tag in abstract view" title="New [Indexed for MEDLINE] status tag in abstract view" /><br />
<strong>Figure 4. New [Indexed for MEDLINE] status tag in abstract view.</strong>
</div>
<p>
The Abstract display in PubMed will include a status tag only if the citation is indexed for MEDLINE. Additional status tags will still appear in the MEDLINE and XML displays. The citation status search strategies will continue to function as they always have. Please see <a href="https://www.ncbi.nlm.nih.gov/books/NBK3827/table/pubmedhelp.T.status_subsets/">Citation Status Subsets</a> in online help for more information.
