Health Risk Assessment - the leading edge from NTP

The National Toxicology Program, part of the National Institute for Environmental Science of NIH is a great resource for human toxicological information. You can subscribe to the NIEHS newsletter Environmental Factor for updates.

The NTP Office of Health Assessment and Translation has just released a Draft OHAT Approach for Systematic Review and EvidenceIntegration for Literature-based Health Assessments – February 2013 – it provides a seven-step framework for conducting evaluations using principles of systematic review. I particularly like the way step 5 (Rate confidence in the body of evidence)  and Step 6 (Translate confidence ratings into evidence of health effects) are described in Figure 1.
