W. Ray Kim, Keith D. Lindor, Michael Malinchoc, Jan L. Petz, Roberta Jorgensen, E. Rolland Dickson – 30 December 2003 – The NIDDK‐QA instrument, developed and widely used in liver transplant recipients, assesses quality of life (QOL) in four domains, including liver disease symptoms, physical function, health satisfaction, and overall well‐being.
