Perhaps you should try some spelling variations:
"significantly linked decrease" » "significantly longer decrease" (Expand Search), "significantly altered decrease" (Expand Search), "significantly higher decrease" (Expand Search), "significantly marked decrease" (Expand Search), "significantly linear decrease" (Expand Search)
"significantly better decrease" » "significantly greater decrease" (Expand Search), "significantly higher decrease" (Expand Search), "significantly lower decrease" (Expand Search), "significantly teer decrease" (Expand Search), "significantly between decreased" (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: "((\"significantly linked decrease\") OR (\"significantly better decrease\"))~".
• Removing quotes may allow a broader search: (( significantly linked decrease ) OR ( significantly better decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (("significantly linked decrease") OR ("significantly better decrease"))*.
