What is quality of evidence?
The Quality of Evidence score shows you how much scientific research supports each health report, helping you understand which insights are backed by the strongest science. You can filter reports by this score on the Health Reports page.
Understanding the Quality of Evidence Score
Our Quality of Evidence score rates the scientific strength of each genetic model on a scale of 0 to 5. A higher score means more robust research validates that finding.
The Five-Point Scale
- Score 0: Preliminary or Questionable Data
- The genetic model is based on incomplete or uncertain data. This information may not reflect actual genetic predispositions. We recommend approaching it cautiously and not making health decisions based on it alone.
- Score 1: Minimal Scientific Support
- The genetic model lacks substantial evidence. It has very little chance of being accurate. More research is needed before drawing conclusions.
- Score 2: Low-Quality Evidence
- There is limited scientific support for this model. It has a low probability of reflecting actual genetic predispositions. Additional research would strengthen confidence in this finding.
- Score 3: Moderate-Quality Evidence
- There is moderate scientific support, meaning the finding has an average chance of being accurate. Keep watching for future research improvements.
- Score 4: High-Quality Evidence
- Strong research supports this genetic model, giving it a good chance of being accurate. However, additional validation data would further increase confidence.
- Score 5: Very High-Quality Evidence
- This finding has high-quality research support and has been validated by additional studies. It has a high probability of reflecting actual genetic predispositions.
How We Evaluate Evidence Quality
We assess each genetic model by examining:
- Sample size and number of cases in studies
- Study design and potential confounding factors
- Participant ethnicity and diversity
- Number of genetic variants available
- Statistical strength and model quality metrics
While the Quality of Evidence score is a valuable guide, consider it alongside other factors and consult with healthcare professionals about health decisions. We're committed to giving you reliable, science-backed information to support your health journey.
