  1. d-ROMs determination of reactive oxidative metabolites, BAP biological antioxidant potential, MDA malondialdehyde, OSI oxidative stress index
  2. P-significance for the differences within each category division (e.g. change in values at female and at male horses separately)
  3. Pa-significance for the difference between the two categories (e.g. change in values at female vs. male horses)
