[1] All estimates come from a single multivariate linear regression model. The total model r2 was 0.21 [2] The model was fit using log10 transformed urine 1-OHPG concentrations. [3] All P-values come from F-tests. [4] Subjects reporting current smoking or a cotinine value greater then 1 were considered smoke exposed. |
