OHAT Evaluation Process

The NTP Office of Health Assessment and Translation develops literature-based evaluations to reach conclusions about potential human health hazards and to examine the state of the science. The output from an evaluation can vary including, but not limited to: NTP Monograph, state of the science workshop report, or peer-reviewed journal publication. All evaluations follow a similar process with opportunities for external scientific, public, and interagency input.
 7 steps of the NTP Approach for Systematic Review and Evidence Integration for Literature-based Health Assessments are included on the OHAT Evaluation Process schematic in the PDF file with the same name listed above the schematic.

Systematic Review

In 2012, OHAT began implementing systematic review methodology to carry out these evaluations (Birnbaum et al 2013, Rooney et al. 2014).
