Perhaps you should try some spelling variations:
decrease training » increased training (Expand search), disease training (Expand search), release training (Expand search)
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 pro » decrease or (Expand search), decrease food (Expand search), decrease treg (Expand search)
pro decrease » to decrease (Expand search), or decrease (Expand search), price 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: "(( decrease pro decrease training program ) OR ( decrease _ decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease pro decrease training program ) OR ( decrease _ decrease lesions decrease ))*.
