Perhaps you should try some spelling variations:
disease reporting » disease report (Expand search), disease reported (Expand search), disease presenting (Expand search)
reporting object » reporting effect (Expand search), reporting affects (Expand search), learning object (Expand search)
decrease their » 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), decreased to (Expand search), decrease or (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (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 their decrease ) OR ( decrease the disease reporting object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease their decrease ) OR ( decrease the disease reporting object ))*.
