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 their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), or decrease (Expand search), of decrease (Expand search)
toc et » tic et (Expand search), moc et (Expand search), topic et (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 their decrease lesions decrease ) OR ( decrease on decrease toc et ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease their decrease lesions decrease ) OR ( decrease on decrease toc et ))*.
