candida protese » candida presence (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and increase » and increases (Expand search), and increased (Expand search)
decrease l » decrease il (Expand search), decrease _ (Expand search), decrease β (Expand search)
l decrease » _ decrease (Expand search), α decrease (Expand search), to 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 l decrease candida protese ) OR ( decrease risk decrease AND increase ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease l decrease candida protese ) OR ( decrease risk decrease and increase ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease l decrease candida protese ) OR ( decrease risk decrease and increase ))*.
