Perhaps you should try some spelling variations:
decrease abortive » decreases aortic (Expand search), decrease overtime (Expand search)
abortive effect » additive effect (Expand search), additive effects (Expand search), adaptive effects (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)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (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), and decrease (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 the decrease NOT decrease ) OR ( decrease with decrease abortive effect ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease the decrease not decrease ) OR ( decrease with decrease abortive effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the decrease not decrease ) OR ( decrease with decrease abortive effect ))*.
