Perhaps you should try some spelling variations:
decreased rate » increased rate (Expand search), decreased base (Expand search), decreased native (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 or (Expand search)
toc decrease » to decrease (Expand search), not decrease (Expand search), of decrease (Expand search)
decrease the » decreases the (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search), _ decrease (Expand search)
in stems » in stem (Expand search), in systems (Expand search), in steers (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: "(( decreased rate decrease toc decrease ) OR ( decrease the decrease in stems ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased rate decrease toc decrease ) OR ( decrease the decrease in stems ))*.
