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