Fig. 5From: An ambient-temperature storage and stabilization device performs comparably to flash-frozen collection for stool metabolomics in infantsRepeat samples from the same individual were compared by paired t-test, separately for the Frozen and OMNImet.GUT collections. The number of metabolites in each biochemical class that increased (up; solid bars) or decreased (down; hatched bars) with p < 0.05 at timepoint 2 relative to timepoint 1 is plotted for Frozen (blue) and OMNImet.GUT (orange) sample setsBack to article page
