Perhaps you should try some spelling variations:
"8 cases increased" » "8 rate increased" (Expand Search), "8 levels increased" (Expand Search), "_ cases increased" (Expand Search), "3 cases increased" (Expand Search), "19 cases increased" (Expand Search)
"a marker decrease" » "a marked decrease" (Expand Search), "a larger decrease" (Expand Search), "a marked increase" (Expand Search), "_ marker decrease" (Expand Search), "_ markers decrease" (Expand Search)
"via large decrease" » "via marked decrease" (Expand Search), "via large increases" (Expand Search), "via large degree" (Expand Search), "a large decrease" (Expand Search)

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: "((\"8 cases increased\") OR (((\"a marker decrease\") OR (\"via large decrease\"))))~".
• Removing quotes may allow a broader search: (( 8 cases increased ) OR ((( a marker decrease ) OR ( via large decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("8 cases increased") OR ((("a marker decrease") OR ("via large decrease"))))*.
