Perhaps you should try some spelling variations:
response decreasing » response increasing (Expand search), response decrease (Expand search), despite decreasing (Expand search)
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
decreasing costs » decreasing cost (Expand search), decreasing rest (Expand search), decrease costs (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)
il decrease » l decrease (Expand search), will decrease (Expand search), oil decreases (Expand search)
costs based » cost based (Expand search), cots based (Expand search), hosts based (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 il decrease ) OR ( decrease response decreasing costs based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease il decrease ) OR ( decrease response decreasing costs based ))*.
