Perhaps you should try some spelling variations:
kelly's criterion » kelly criterion, weyl's criterion, levy's criterion
linker's criteria » funder's criteria, concerns criteria, line criteria
caliber arterial » catheter arterial, after arterial, alters arterial
cancer arterial » cancer bacterial, cancer materials, after arterial

You may be able to get more results by adjusting your search query.

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