Perhaps you should try some spelling variations:
decreases ovarian » decreases organ (Expand search), decreases cardiac (Expand search), decreases pain (Expand search)
ovarian pattern » ovarian patterns (Expand search), variant pattern (Expand search), invariant pattern (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)
toc decreases » c decreases (Expand search), oic decreases (Expand search), co2 decreases (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (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 that decrease will decrease ) OR ( decrease toc decreases ovarian pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease that decrease will decrease ) OR ( decrease toc decreases ovarian pattern ))*.
