AASLD guidelines classification scheme
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
AASLD (American Association of Study of Liver Disease) provides recommendations for various liver diseases. It develops clinical practice guidelines which are supported by a high level of scientific evidence. They assist in appropriate health care to patients. The clinical practice guidelines should not be looked as "standards of care". They are provided to aid in diagnosis and management of liver diseases.[1]
Classification of Recommendations
AASLD recommendations are classified into five grades based on quality of evidence.[2]
| Grade | Definition |
|---|---|
| Grade I | Randomized controlled trials |
| Grade II - 1 | Controlled trials without randomization |
| Grade II - 2 | Cohort or case-control analytic studies |
| Grade II - 3 | Multiple time series, dramatic uncontrolled experiments |
| Grade III | Opinions of respected authorities, descriptive epidemiology |
