 					<p class="paragraph">ISARIC also provides a set of analytic tools called VERTEX, designed to perform the analyses outlined in the SAP using ISARIC's data structures. VERTEX generates tables, visualisations, and results using Python code, and displays this information in insight panels, for each relevant research question or study endpoint.</p>
 					<p class="paragraph">The VERTEX insight panels are built using reproducible analytical pipelines. VERTEX is designed to allow ISARIC members and the broader scientific community to develop, contribute to and share new reproducible analytical pipelines. This will help to broaden the scope of the data analysis tools.</p>
