Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
disease lesions » disease lessons (Expand search), diseases lessons (Expand search)
decrease usage » decrease age (Expand search), decreased use (Expand search)
usage pattern » usage patterns (Expand search), use pattern (Expand search), image pattern (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or disease » ear disease (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease OR disease lesions decrease ) OR ( decrease _ decrease usage pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or disease lesions decrease ) OR ( decrease _ decrease usage pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or disease lesions decrease ) OR ( decrease _ decrease usage pattern ))*.
