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