patients 10.5 » patients 10.1, patients 10.6, patients 14.5
patients 1.8 » patients 10.1, patients 10.6, patients 11.6
wing yan » wang yan, wing ian, wing tan
yang fan » zhang fan, yang yang, yang jin
dean » dewan, jean, den

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: wing yan ((yang fan) OR (yang dean)) do ((patients 1.8) OR (patients 10.5)) among masters ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan ((yang fan) OR (yang dean)) do ((patients 1.8) or (patients 10.5)) among masters ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan ((yang fan) OR (yang dean)) do ((patients 1.8) or (patients 10.5)) among masters ;*.
