Jadad Score; Oxford Scale
DefinitionThis section has been translated automatically.
The Jadad Scale is used to assess the quality of the methodology of clinical intervention studies. The Jadad Scale was designed in 1996 by Alejandro Jadad, a Colombian physician. The aim of this scale is to evaluate the methodology used in clinical studies.
General informationThis section has been translated automatically.
The Jadad Scale is validated and includes 5 questions concerning randomization, blinding and description of patient courses (drop-outs):
- Was it described whether the study was randomized?
- Was the description of the randomisation sufficient / appropriate?
- Was the study described as double-blind?
- Was the blinding appropriate?
- Were all patient courses explained?
A point is awarded for each applicable question, so that a score of maximum 5 is calculated. Intervention studies with a score < 3 are rated as inadequate.
The limitation of this simple scale is a limited applicability, e.g. the Oxford Scale cannot be used in non-interventional studies (NIS).
