Perhaps you should try some spelling variations:
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
disease costs » disease cost (Expand search), disease cross (Expand search), disease cases (Expand search)
the processes » the process (Expand search), the processing (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
decrease toc » decrease of (Expand search), decreased to (Expand search), decrease food (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (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 toc decrease the processes ) OR ( disease costs decrease rate decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease the processes ) OR ( disease costs decrease rate decrease ))*.
