Perhaps you should try some spelling variations:
decrease leaming » decreases weaning (Expand search), decreases healing (Expand search), decrease lodging (Expand search)
leaming objects » learning objects (Expand search), naming objects (Expand search), teaching objects (Expand search)
decreased loss » increased loss (Expand search), decreased blood (Expand search), decreased risk (Expand search)
loss decrease » loss decreases (Expand search), not decrease (Expand search), of decrease (Expand search)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 in decreased loss decrease ) OR ( decrease to decrease leaming objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decreased loss decrease ) OR ( decrease to decrease leaming objects ))*.
