decrease after » increase after (Expand search), disease after (Expand search)
hiv increases » hiv increase (Expand search), v increases (Expand search), ai increases (Expand search)

and decrease » and decreases (Expand search), and decreased (Expand search), and increase (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 toc decrease AND decrease ) OR ( decrease hiv increases decrease after ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease toc decrease and decrease ) OR ( decrease hiv increases decrease after ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease and decrease ) OR ( decrease hiv increases decrease after ))*.
