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 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)
decrease low » decreases low (Expand search), decreases flow (Expand search), decrease of (Expand search)
low decrease » flow decrease (Expand search), loss decrease (Expand search), to decrease (Expand search)
decrease due » decrease the (Expand search), increase due (Expand search), decrease age (Expand search)
due pattern » the pattern (Expand search), use pattern (Expand search), eye pattern (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 toc decrease low decrease ) OR ( decrease lesions decrease due pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease low decrease ) OR ( decrease lesions decrease due pattern ))*.
