Fig 2. Biochemical importance plot based on Random Forest classification of metabolic profile from normoxic and hypoxic carotid arteries from (A) Fetus (B) Newborn and (C) Adults.

The metabolites are plotted according to the increasing importance to group separation to elucidate the metabolic fingerprint for hypoxia in fetal carotid arteries as compared to normoxic counterpart. N = 8 in each group.
