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