Perhaps you should try some spelling variations:
"ct largest decrease" » "ct largest decreases" (Expand Search), "ct larger decrease" (Expand Search), "ct marked decrease" (Expand Search), "_ largest decrease" (Expand Search)
"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)
"aui values decrease" » "aui values increased" (Expand Search), "auc values decrease" (Expand Search), "ani values decrease" (Expand Search), "ari values decrease" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ic cases increased") OR ("aui values decrease"))) OR ("ct largest decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ic cases increased\") OR (\"aui values decrease\"))) OR (\"ct largest decrease\"))*".
• Removing quotes may allow a broader search: (((( ic cases increased ) OR ( aui values decrease ))) OR ( ct largest decrease ))*.
