Table 5. Results from analysis of FACES data set using LM and LM-int.

Table includes effect estimates ( $\hat{β}$ ), 95% confidence intervals, and associated p-values for all main effects in LM and LM-int plus the interaction effects in LM-int with p-values ≤ 0.10. The regression coefficient $\hat{β}$ is the expected change in FEV₁ for a 1 standard deviation increase in the square root transformed exposures.
