Perhaps you should try some spelling variations:
"significantly weaker decrease" » "significantly greater decrease" (Expand Search), "significantly better decrease" (Expand Search), "significantly related decrease" (Expand Search), "significantly teer decrease" (Expand Search), "significantly water decreases" (Expand Search)
"significantly less decrease" » "significantly lower decrease" (Expand Search), "significantly reduce decrease" (Expand Search), "significantly better decrease" (Expand Search), "significantly mean decrease" (Expand Search), "significantly teer decrease" (Expand Search), "significantly we 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: "((\"significantly weaker decrease\") OR (\"significantly less decrease\"))~".
• Removing quotes may allow a broader search: (( significantly weaker decrease ) OR ( significantly less decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (("significantly weaker decrease") OR ("significantly less decrease"))*.
