Perhaps you should try some spelling variations:
linker's criteria » concerns criteria, line criteria
funder's criteria » concerns criteria, funding criteria, pde's criteria
catheter arterial » catheter material, transcatheter arterial, after arterial
well's criterion » weyl's criterion, kelly's criterion, kelly criterion
cancer arterial » cancer bacterial, cancer materials, caliber arterial

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: "((\"well's criterion\") or (((\"((linker's criteria) OR (funder's criteria))\") or (\"((cancer arterial) OR (catheter arterial))\"))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"well's criterion\\") or (((\\"((linker's criteria) OR (funder's criteria))\\") or (\\"((cancer arterial) or (catheter arterial))\\"))))\"".
• Removing quotes may allow a broader search: (( well's criterion ) or ((( ((linker's criteria) OR (funder's criteria)) ) or ( ((cancer arterial) or (catheter arterial)) )))).
