Table 6. Results from analysis of FACES data set using NPBr and NPB.

Table shows estimates ($\widehat{\beta }$), 95% credible intervals, and posterior inclusion probabilities (PIP) for main effect exposures in NPB and NPBr. The regression coefficient $\widehat{\beta }$ is the expected change in FEV₁ for a 1 standard deviation increase in the square root transformed exposures. All interaction effects in NPB had posterior inclusion probabilities below 0.12.
