  1. Note: There are slight discrepancies in weighted count totals due to missing (non-response) data. P-values were derived using Pearson’s chi-square test. Asterisks within cells indicate P-values derived from further analysis for selected variables which compares each 2008 and 2013 row value to the base year (2003) of that row through bivariate logistic regression, and where *** P <  0.001, ** P <  0.010, and * P <  0.050. Odds ratios and P-values from the further analyses are cited in the narratives and shown in table form in Appendix 2
