Perhaps you should try some spelling variations:
"i values increased" » "i cases increased" (Expand Search), "i also increased" (Expand Search), "i rate increased" (Expand Search), "_ values increased" (Expand Search)
"i largest decrease" » "i largest decreases" (Expand Search), "i larger decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"b marked decrease" » "b marked increase" (Expand Search), "_ marked decrease" (Expand Search), "a marked decrease" (Expand Search), "_ market decrease" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("b marked decrease") OR ((("i values increased") OR ("i largest decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"b marked decrease\") OR (((\"i values increased\") OR (\"i largest decrease\"))))".
• Removing quotes may allow a broader search: (( b marked decrease ) OR ((( i values increased ) OR ( i largest decrease )))).
• Adding a wildcard symbol may retrieve word variants: (("b marked decrease") OR ((("i values increased") OR ("i largest decrease"))))*.
