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), "i marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"_ large decrease" » "_ marked decrease" (Expand Search), "_ large increases" (Expand Search), "_ large degree" (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 values increased\") OR (((\"i largest decrease\") OR (\"_ large decrease\"))))~".
• Removing quotes may allow a broader search: (( i values increased ) OR ((( i largest decrease ) OR ( _ large decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("i values increased") OR ((("i largest decrease") OR ("_ large decrease"))))*.
