Perhaps you should try some spelling variations:
"152 cases increased" » "152 rate increased" (Expand Search), "152 levels increased" (Expand Search), "19 cases increased" (Expand Search), "16 cases increased" (Expand Search), "1 cases increased" (Expand Search)
"_ large decrease" » "_ marked decrease" (Expand Search), "_ large increases" (Expand Search), "_ large degree" (Expand Search)
"c large decrease" » "c marked decrease" (Expand Search), "c large increases" (Expand Search), "c large degree" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search), "b 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: "((((\"_ large decrease\") OR (\"c large decrease\"))) OR (\"152 cases increased\"))~".
• Removing quotes may allow a broader search: (((( _ large decrease ) OR ( c large decrease ))) OR ( 152 cases increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ large decrease") OR ("c large decrease"))) OR ("152 cases increased"))*.
