Perhaps you should try some spelling variations:
"c values increased" » "c cases increased" (Expand Search), "c dalys increased" (Expand Search), "c also increased" (Expand Search), "ct values increased" (Expand Search), "_ values increased" (Expand Search), "auc values increased" (Expand Search)
"i largest decrease" » "i larger decrease" (Expand Search), "i marked decrease" (Expand Search), "_ largest decrease" (Expand Search), "i large decrease" (Expand Search)
"i values decrease" » "_ 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 decrease\") OR (\"c values increased\"))) OR (\"i largest decrease\"))~".
• Removing quotes may allow a broader search: (((( i values decrease ) OR ( c values increased ))) OR ( i largest decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("i values decrease") OR ("c values increased"))) OR ("i largest decrease"))*.
