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)
"i marked decrease" » "i marked increase" (Expand Search), "_ marked decrease" (Expand Search), "_ market decrease" (Expand Search), "_ marker decrease" (Expand Search)
"a large decrease" » "a large increases" (Expand Search), "a large degree" (Expand Search), "_ 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 (((\"i marked decrease\") OR (\"a large decrease\"))))~".
• Removing quotes may allow a broader search: (( 8 cases increased ) OR ((( i marked decrease ) OR ( a large decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("8 cases increased") OR ((("i marked decrease") OR ("a large decrease"))))*.
