Perhaps you should try some spelling variations:
patients risk » patients links, patients si, patients view
patient risk » patient task, patient cost, orient risk
among peers » among ers, among users, among letters
wang liang » wang yang
liang yang » liang ying, wang yang, yang yang
dean lose » can lose

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: "wang liang yang dean lose ((patients risk) OR (patient risk)) among peers ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang yang dean lose ((patients risk) OR (patient risk)) among peers ;*.
