Perhaps you should try some spelling variations:
increase their » increase the (Expand search), increases the (Expand search), increased the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
the basel » the base (Expand search), the basal (Expand search), the basic (Expand search)

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

• Removing quotes may allow a broader search: (( increase their decrease of decrease ) OR ( decrease NOT decrease the basel ))~.
