Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease after » increase after (Expand search), disease after (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
after basic » after lasik (Expand search), after brazil (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: "(( decrease lesions decrease toc decrease ) OR ( decrease in decrease after basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease toc decrease ) OR ( decrease in decrease after basic ))*.
