Perhaps you should try some spelling variations:
"100 ng decrease" » "100 _ decrease" (Expand Search), "100 nm decrease" (Expand Search), "10 ng decrease" (Expand Search), "100 mg decrease" (Expand Search)
"5 ht decrease" » "5 _ decrease" (Expand Search)
"_ wt decrease" » "_ _ decrease" (Expand Search)
"_ we decrease" » "_ _ decrease" (Expand Search), "_ web decrease" (Expand Search), "_ e decrease" (Expand Search), "_ fe 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: "((\"100 ng decrease\") OR (((((\"5 ht decrease\") OR (\"_ wt decrease\"))) OR (\"_ we decrease\"))))~".
• Removing quotes may allow a broader search: (( 100 ng decrease ) OR ((((( 5 ht decrease ) OR ( _ wt decrease ))) OR ( _ we decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("100 ng decrease") OR ((((("5 ht decrease") OR ("_ wt decrease"))) OR ("_ we decrease"))))*.
