Perhaps you should try some spelling variations:
of effectively » not effectively (Expand search), how effectively (Expand search), of effective (Expand search)
decrease toc » decrease the (Expand search), decreased to (Expand search), decrease or (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease on » decrease in (Expand search), decrease or (Expand search), decrease and (Expand search)
on decrease » on decreased (Expand search), or decrease (Expand search), of decrease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
decrease of » decrease in (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease toc decrease on decrease ) OR ( decrease at decrease of effectively ))~.
