-This track set shows GWAS meta-analyses from the 
-<a href='https://covid19hg.org'>COVID-19 Host Genetics Initiative</a>.
+This track set shows <b>GWAS meta-analyses</b> from the 
+<a target=_blank href="https://www.covid19hg.org/"><b>COVID-19 host genetics initiative (COVID-19 hg)</b></a>, 
+a collaborative work intended to encourage the sharing of resources to
+facilitate Covid-19 host genetics research. COVID-19 hg organizes analytical activities across
+different studies to identify genetic determinants of SARS-CoV-2 infection susceptibility and 
+severity of disease, and provides a platform to share the results from such activities, as well as 
+the individual-level data where possible.
+</p>
 
+<p>
+The studies are focused on specific phenotypes that can benefit
+from maximal sample size. The primary analysis focuses on Covid-19 disease severity.
 Two studies are represented in this track:
 
 <ul>
-<li>B2: hospitalized covid vs. population (3199 cases from 8 studies)</li>
-<li>C2: covid vs. population (6696 cases from 18 studies)</li>
+<li><b>ANA_B2_V2</b>: hospitalized covid vs. population (3199 cases from 8 studies)</li>
+<li><b>ANA_C2_V2</b>: covid vs. population (6696 cases from 18 studies)</li>
 </ul>
 
-Data underlying these tracks was obtained from Release 3 (June 2020) results provided at
-<a href='https://www.covid19hg.org/results/'>https://www.covid19hg.org/results</a>.

+
+<H2>Methods</H2>
+<p>
+Data was generated from genome wide SNP array, exome and genome sequencing, leveraging the impact 
+of both common and rare variants. Statistical analysis takes into account differences between 
+sexes, ancestries, and date of sample collection. More information about the prospective studies, 
+processing pipeline, results and data sharing can be found 
+<a target=_blank href="https://www.covid19hg.org/about/">here</a>.
