Analytes are ranked from top to bottom based on the strength of the association. Spearman’s correlation coefficient, 95% CI, and p values were calculated automatically by Prism 8. The Benjamini–Hochberg method was used to correct for multiple comparisons with the false discovery rate set to 5%. q values obtained from correcting for multiple comparisons are reported
