Perhaps you should try some spelling variations:
methylation patterns » migration patterns (Expand search)
decrease methylation » decrease migration (Expand search), accurate methylation (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » and decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease pro (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 faster decrease the decrease ) OR ( decrease to decrease methylation patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease the decrease ) OR ( decrease to decrease methylation patterns ))*.
