Perhaps you should try some spelling variations:
decrease lowering » decrease lodging (Expand search), decrease owing (Expand search), decrease suffering (Expand search)
lowering effects » lowering effect (Expand search), loading effects (Expand search), looping effects (Expand search)
decreased rate » increased rate (Expand search), decreased base (Expand search), decreased native (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
decrease hiv » decrease in (Expand search), decrease their (Expand search), decreased high (Expand search)
hiv decrease » via decrease (Expand search), hiv increase (Expand search), will 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: "(( decreased rate decrease hiv decrease ) OR ( decrease _ decrease lowering effects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased rate decrease hiv decrease ) OR ( decrease _ decrease lowering effects ))*.
