Perhaps you should try some spelling variations:
decrease vegetation » increased vegetation (Expand search), decrease migration (Expand search), dense vegetation (Expand search)
vegetation patterns » migration patterns (Expand search), interaction patterns (Expand search), methylation patterns (Expand search)
decrease life » decrease liver (Expand search), increase life (Expand search), decreases liver (Expand search)
life decrease » life decreases (Expand search), life decreased (Expand search), life increase (Expand search)
decrease urea » decrease treg (Expand search), decrease burden (Expand search), decreases areas (Expand search)
urea decrease » the decrease (Expand search), or decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease NOT decrease life decrease ) OR ( decrease urea decrease vegetation patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease life decrease ) OR ( decrease urea decrease vegetation patterns ))*.
