					<description><![CDATA[We next investigated underlying factors that determine the number of significant co-operative and antagonistic interactions for each metabolite in MPCA. The number of protein co-variates with each metabolite did not correlate with the degree of metabolite abundance variation across the DO cohort (Extended Data Fig. 3a). Instead, the number of recapitulated metabolite–protein relationships was positively [&#8230;]]]></description>
