Perhaps you should try some spelling variations:
significant decrease » significant increase (Expand Search), significantly increased (Expand Search)
significant size » significant side (Expand Search), significant sex (Expand Search), significant snp (Expand Search)
decrease cgas » increased cgas (Expand Search), increases cgas (Expand Search)
size decrease » sizes decrease (Expand Search), size increase (Expand Search), size increased (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: "(( significant decrease cgas ) OR ( significant size decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( significant decrease cgas ) OR ( significant size decrease ))*.
