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 flow » decreases flow (Expand search), decrease low (Expand search), decrease food (Expand search)
flow decrease » flow increase (Expand search), to decrease (Expand search), not decrease (Expand search)
decrease how » decrease low (Expand search), decrease hiv (Expand search), decrease on (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
how objects » new objects (Expand search), iot objects (Expand search), from objects (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 lesions decrease of decrease ) OR ( decrease flow decrease how objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease of decrease ) OR ( decrease flow decrease how objects ))*.
