Perhaps you should try some spelling variations:
"b large decrease" » "b marked decrease" (Expand Search), "b large increases" (Expand Search), "b large degree" (Expand Search), "a large decrease" (Expand Search), "i large decrease" (Expand Search), "_ larger decrease" (Expand Search)
"_ large decrease" » "_ marked decrease" (Expand Search), "_ large increases" (Expand Search), "_ large degree" (Expand Search)
"wt levels increased" » "atp levels increased" (Expand Search), "alt levels increased" (Expand Search), "_ levels increased" (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: "((((\"b large decrease\") OR (\"_ large decrease\"))) OR (\"wt levels increased\"))~".
• Removing quotes may allow a broader search: (((( b large decrease ) OR ( _ large decrease ))) OR ( wt levels increased ))~.
• Adding a wildcard symbol may retrieve word variants: (((("b large decrease") OR ("_ large decrease"))) OR ("wt levels increased"))*.
