Perhaps you should try some spelling variations:
"ic cases increased" » "ic rate increased" (Expand Search), "ic levels increased" (Expand Search), "19 cases increased" (Expand Search), "_ cases increased" (Expand Search), "3 cases increased" (Expand Search)
"i values decrease" » "i values increased" (Expand Search), "i largest decrease" (Expand Search), "_ values decrease" (Expand Search)
"ct larger decrease" » "ct marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "c 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: "((\"ic cases increased\") OR (((\"i values decrease\") OR (\"ct larger decrease\"))))~".
• Removing quotes may allow a broader search: (( ic cases increased ) OR ((( i values decrease ) OR ( ct larger decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("ic cases increased") OR ((("i values decrease") OR ("ct larger decrease"))))*.
