Measurement of health status. Ascertaining the minimal clinically important difference.
An approach to elucidating the significance of changes in score in quality of life instruments by comparing them to global ratings of change is developed, and a plausible range within which the minimal clinically important difference (MCID) falls is established. Expand
GRADE guidelines: 3. Rating the quality of evidence.
The approach of GRADE to rating quality of evidence specifies four categories-high, moderate, low, and very low-that are applied to a body of evidence, not to individual studies. Expand

A measure of quality of life for clinical trials in chronic lung disease.
It has been shown that the questionnaire is precise, valid, and responsive and can therefore serve as a useful disease specific measure of quality of life for clinical trials. Expand
Validity and Reliability of a Questionnaire for Measuring Child Oral-health-related Quality of Life
The results suggest that the CPQ11-14, a self-report measure of the impact of oral and oro-facial conditions on 11- to 14-year-old children, is valid and reliable. Expand
