Perhaps you should try some spelling variations:
decrease variable » decrease variability (Expand search), decreases available (Expand search), discrete variable (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)
variable pattern » variable matter (Expand search), variate pattern (Expand search), variable water (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)

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 lesions decrease ) OR ( decrease NOT decrease variable pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease lesions decrease ) OR ( decrease NOT decrease variable pattern ))*.
