What is quality of evidence?

The Quality of Evidence score provides you with an easy way to determine which reports have more scientific evidence than others, ensuring that you have reliable information to guide your health choices.

You may filter reports using Quality of Evidence score filter on the Health Reports page, and also see the score on each report shortcut.

What is the Quality of Evidence Score?

The Quality of Evidence score is a measure that quantifies the level of scientific support for a particular report. It reflects the extent to which the available evidence supports the report's validity. The score is presented on a scale of 0 to 5, with 0 indicating no evidence and 5 denoting strong scientific backing.

Understanding the Scoring System:


0: The genetic model is based on preliminary, incomplete, or questionable data. It is unlikely to reflect actual genetic predispositions. While it might not be entirely unfounded, we recommend approaching this information carefully and not making any decisions based on it.

1: The genetic model lacks substantial scientific evidence. It has a very low chance of reflecting actual genetic predispositions. Further research is needed before making any conclusions.

2: There is low-quality evidence to support the genetic model. It has a low chance of reflecting actual genetic predispositions. Further research is needed before making solid conclusions.

3: There is moderate-quality evidence supporting the genetic model. It has an average chance of reflecting actual genetic predispositions. Keeping an eye on future research improvements is recommended.

4: There is high-quality evidence supporting the genetic model. It has a decent chance of reflecting actual genetic predispositions. However, its accuracy has yet to be validated by additional data.

5: There is high-quality evidence supporting the genetic model. It has also been validated by additional data. It has a high chance of reflecting actual genetic predispositions.


We estimate the evidence for each genetic model based on the quality of the source studies. We look at the sample size, number of cases, confounding factors, ethnicity, and more. We also consider the number of available genetic variants, along with complex statistical parameters and graphs that describe model quality.

Please note that while the Quality of Evidence score is a valuable tool, it is still important to consider it alongside other factors and consult with healthcare professionals when necessary. We are dedicated to providing you with reliable and evidence-based information to support your health journey.
