Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
different effects » differential effects (Expand search)
create different » creates different (Expand search), creates difference (Expand search), creating different (Expand search)
response create » response rate (Expand search), response decrease (Expand search), response increase (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 or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to 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 toc decrease OR decrease ) OR ( decrease response create different effects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease toc decrease or decrease ) OR ( decrease response create different effects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease or decrease ) OR ( decrease response create different effects ))*.
