Further stratified analyses from high Jadad score
studies showed that green tea significantly reduced fasting insulin concentrations (-1.
To supplement the Jadad score
, using Verhagen et al.
All were randomised, but varied in study quality with a median Jadad score
Studies have also found the inter-rater reliability of the PEDro Scale to be of an appropriate standard whilst assessing RCTs (Maher et al 2003, Tooth et al 2005) and when compared with the Jadad score
, the PEDro Scale is more comprehensive in assessing methodological quality (Bhogal et al 2005).
4) The Jadad score
has been validated as a scale for assessing trial reporting quality and is used to distinguish low-quality from high-quality studies.
Tabella III: Jadad scale JADAD SCORE

RCTs with a Jadad score
of more than or equal to 3 can be considered as a medium to good quality study.
We used the Jadad score
to calculate the quality of the clinical trials reported in the media.
Because we are unaware of any scoring system to quantify the rigor of diagnostic studies, we derived a scoring system using the Jadad score
for therapeutic studies as a model.
Watson and his associates conducted a literature search of PubMed, Medline, and the Cochrane databases and found 42 randomized trials of oral agents for neuropathic pain with a Jadad score
(a measure of study design and quality) of 3 or more.
Data were extracted by two independent reviewers, and methodological quality was assessed using the Jadad score
and key aspects of the Cochrane risk of bias.
Five of the 10 RCTs reached more than three points on the Jadad score
