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 with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (Expand search)
toc decreases » c decreases (Expand search), oic decreases (Expand search), co2 decreases (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease AND decrease with decrease ) OR ( decrease toc decreases ovarian pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease with decrease ) OR ( decrease toc decreases ovarian pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease with decrease ) OR ( decrease toc decreases ovarian pattern ))*.
