during disease » urine disease (Expand search), ring disease (Expand search), using disease (Expand search)
decrease same » decrease age (Expand search), decreased base (Expand search), decreases salt (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)

and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
same object » time object (Expand search), based object (Expand search), large object (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 during disease ) OR ( decrease AND decrease same object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease toc decrease during disease ) OR ( decrease and decrease same object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease during disease ) OR ( decrease and decrease same object ))*.
