Perhaps you should try some spelling variations:
decrease variant » decreases ovarian (Expand search), decreased ovarian (Expand search), decrease asian (Expand search)
foods decreases » loss decreases (Expand search)
variant pattern » invariant pattern (Expand search), variate pattern (Expand search), ovarian patterns (Expand search)
decrease foods » decrease food (Expand search), decreases food (Expand search), decreased food (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), the decrease (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)

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 NOT decrease foods decreases ) OR ( decrease AND decrease variant pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease foods decreases ) OR ( decrease and decrease variant pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease foods decreases ) OR ( decrease and decrease variant pattern ))*.
