Perhaps you should try some spelling variations:
"_ mg decrease" » "_ _ decrease" (Expand Search), "_ m decrease" (Expand Search), "_ 5g decrease" (Expand Search), "_ ag decrease" (Expand Search)
"5 wt decrease" » "5 _ decrease" (Expand Search), "_ wt decrease" (Expand Search), "5 ht decrease" (Expand Search), "2 wt decrease" (Expand Search)
"50 ms decrease" » "50 _ decrease" (Expand Search)
"50 a decrease" » "50 _ decrease" (Expand Search), "50 _ decreased" (Expand Search), "50 _ decreases" (Expand Search), "5 a decrease" (Expand Search), "50 i 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: "((((\"50 a decrease\") OR (((\"_ mg decrease\") OR (\"5 wt decrease\"))))) OR (\"50 ms decrease\"))~".
• Removing quotes may allow a broader search: (((( 50 a decrease ) OR ((( _ mg decrease ) OR ( 5 wt decrease ))))) OR ( 50 ms decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("50 a decrease") OR ((("_ mg decrease") OR ("5 wt decrease"))))) OR ("50 ms decrease"))*.
