Perhaps you should try some spelling variations:
"i marked decrease" » "i marked increase" (Expand Search), "_ marked decrease" (Expand Search), "_ market decrease" (Expand Search), "_ marker decrease" (Expand Search)
"ct cases increased" » "ct rate increased" (Expand Search), "ct levels increased" (Expand Search), "c2 cases increased" (Expand Search), "chd cases increased" (Expand Search), "ckd cases increased" (Expand Search)
"i large decrease" » "i large increases" (Expand Search), "i large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "via 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: "((((\"i marked decrease\") OR (\"i large decrease\"))) OR (\"ct cases increased\"))~".
• Removing quotes may allow a broader search: (((( i marked decrease ) OR ( i large decrease ))) OR ( ct cases increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i marked decrease") OR ("i large decrease"))) OR ("ct cases increased"))*.
