Perhaps you should try some spelling variations:
decrease swallowing » disease swallowing (Expand search), decrease following (Expand search), decrease walking (Expand search)
swallowing pattern » swallowing after (Expand search)
decrease soil » decreases soil (Expand search), increase soil (Expand search), decrease il (Expand search)
soil decrease » oil decreases (Expand search), soil increase (Expand search), bail decreases (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (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)

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

• Removing quotes may allow a broader search: (( decrease soil decrease toc decrease ) OR ( decrease will decrease swallowing pattern ))~.
