Appendix D Food Codes for NHANES - OEHHA

efficiency as some of the most common PAHs without cancer potency factors
that are taken in through the diet.
Summary Tcos were calculated using a Random-effects model to pool across
individual PAH-Tcos. OEHHA found no systematic difference between summary
estimates stratified by PAHs with or without cancer potency factors (data not
shown). Therefore, we pooled Tcos for both groups by route of intake (see Table
J.3-7).
Table J.3-7: Random Effects Estimate and 95% Confidence Intervals of
Tcos Stratified by Intake Route and Data Source
Tco (data source) No. PAHs summary estimate (random effects model) LCL UCL
Inhalation 13 1.55 0.731 3.281
Oral (Italian) 9 0.401 0.132 1.218
LCL, lower 95% confidence limit of the mean Tco; UCL, upper 95% confidence
limit of the mean Tco.
