Perhaps you should try some spelling variations:
significantly largest » significantly larger (Expand Search), significantly less (Expand Search), significantly affect (Expand Search)
significantly weaker » significantly greater (Expand Search), significantly better (Expand Search), significantly related (Expand Search)
largest decrease » larger decrease (Expand Search), marked decrease (Expand Search)
weaker decrease » greater decrease (Expand Search), teer decrease (Expand Search), water decreases (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: "(( significantly largest decrease ) OR ( significantly weaker decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( significantly largest decrease ) OR ( significantly weaker decrease ))*.
