Perhaps you should try some spelling variations:
"_ fed decrease" » "_ _ decrease" (Expand Search), "_ feed decrease" (Expand Search)
"5 wt decrease" » "5 _ decrease" (Expand Search), "_ wt decrease" (Expand Search), "5 ht decrease" (Expand Search), "2 wt decrease" (Expand Search)
"5 g decrease" » "5 _ decrease" (Expand Search), "5 _ decreased" (Expand Search), "5 _ decreases" (Expand Search), "5 μg decrease" (Expand Search)
"_ e decrease" » "_ _ decrease" (Expand Search), "_ _ decreased" (Expand Search), "_ _ decreases" (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: "((\"5 g decrease\") OR (((((\"_ e decrease\") OR (\"_ fed decrease\"))) OR (\"5 wt decrease\"))))~".
• Removing quotes may allow a broader search: (( 5 g decrease ) OR ((((( _ e decrease ) OR ( _ fed decrease ))) OR ( 5 wt decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("5 g decrease") OR ((((("_ e decrease") OR ("_ fed decrease"))) OR ("5 wt decrease"))))*.
