Perhaps you should try some spelling variations:
decrease spatial » decrease survival (Expand search), decrease striatal (Expand search), decrease asian (Expand search)
spatial pattern » spatial patterns (Expand search)
decrease stent » decreased pten (Expand search), decrease std (Expand search), decrease soon (Expand search)
stent decrease » strength decrease (Expand search), events decrease (Expand search), term decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease can » decrease in (Expand search), decrease at (Expand search), decrease on (Expand search)
can decrease » can increase (Expand search), to decrease (Expand search), the 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 AND decrease stent decrease ) OR ( decrease can decrease spatial pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease stent decrease ) OR ( decrease can decrease spatial pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease stent decrease ) OR ( decrease can decrease spatial pattern ))*.
