Perhaps you should try some spelling variations:
among masters » among partners, among farmers, among actors
patients 1.8 » patients 10.1, patients 10.5, patients 10.6
1.8 among » 1.5 among, 19 among, 1 among
yan yang » yang yang, yao yang, dan yang
fan de » van de, aan de
can de » can do, can code, can deal
jan de » van de, aan de
wang » wan, lang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yan yang ((((fan de) OR (can de))) OR (jan de)) patients 1.8 among masters ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yan yang ((((fan de) OR (can de))) or (jan de)) patients 1.8 among masters ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) yan yang ((((fan de) OR (can de))) or (jan de)) patients 1.8 among masters ;*.
