7th IGASS Forum - Liverpool, UK, October 1, 2013

The level of scientific evidence available for the specific disorder of all cases are graded according to the recommendation of the GRADE group (Guyatt et al. 2011), adapted by the Cochrane group. The grades of evidence are:

Grade 1 (high) Grade 2 (moderate), Grade 3 (low) or Grade 4 (very low). 

In addition to this, the strength of recommendation, strong or weak, for or against the treatment each patient received is presented.
The Grade of Evidence reflects the quality of studies performed for the specific diagnosis, the RCT being the highest level and retrospective studies and expert opinion the lowest. The strength of recommendation reflect issues like risk-benefit and cost effectiveness, and does not directly reflect the Grading. For example a surgical procedure may have a very low scientific support, but still be strongly recommended because of potentially catastrophical outcomes if not operated on.
