Note:
Each predictor was tested in a separate model. Model columns 1 and 3 show results of unadjusted analyses, where the predictor was the only independent variable in the model. Model columns 2 and 4 show these results controlling for medication use (Yes [1]/No [0]), smoking status (Yes [1]/No [0]), and age.
Italicized values are less than .05 but become nonsignificant after controlling for multiple comparisons using the Holm-Bonferroni correction. Bolded p-values are significant after controlling for multiple comparisons using the Holm-Bonferroni correction.
