Perhaps you should try some spelling variations:
that increases » that increase (Expand search), what increases (Expand search), diet increases (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
increases not » increases non (Expand search), increases both (Expand search), increases nk (Expand search)
decrease road » decrease food (Expand search), decrease sod (Expand search), decreased rorc (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
road objects » sound objects (Expand search), rigid objects (Expand search), focal objects (Expand search)
decrease by » decreased by (Expand search), decrease in (Expand search), decrease of (Expand search)
by decrease » by decreased (Expand search), may decrease (Expand search), any 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 that increases NOT decrease ) OR ( decrease by decrease road objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease that increases not decrease ) OR ( decrease by decrease road objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease that increases not decrease ) OR ( decrease by decrease road objects ))*.
