Perhaps you should try some spelling variations:
"i larger decrease" » "i marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "i large decrease" (Expand Search), "_ large decrease" (Expand Search)
"ktr cases increased" » "ktr rate increased" (Expand Search), "ktr levels increased" (Expand Search)
"c large decrease" » "c marked decrease" (Expand Search), "c large increases" (Expand Search), "c large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "i large 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: (((("c large decrease") OR ("i larger decrease"))) OR ("ktr cases increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c large decrease\") OR (\"i larger decrease\"))) OR (\"ktr cases increased\"))*".
• Removing quotes may allow a broader search: (((( c large decrease ) OR ( i larger decrease ))) OR ( ktr cases increased ))*.
