  1. Statistically significant p-values are boldfaced. The p-values are raw scores, with the Bonferroni corrected significance threshold of p = 0.004. Number of observations = 455. OR odds ratio; CI confidence interval. Odds Ratio measures the strength of association: OR > 1 indicates greater odds, OR = 1 indicates no difference, and OR < 1 indicates lower odds.
