Perhaps you should try some spelling variations:
in preprocessing » in reprocessing (Expand search), and preprocessing (Expand search), via preprocessing (Expand search)
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (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 to decrease in preprocessing ) OR ( decrease faster decrease during depressed ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease in preprocessing ) OR ( decrease faster decrease during depressed ))*.
