| Notes: For men, Model 1 was based on 36,271 records; Model 2 was based on 34,239 records. For women, Model 1 was based on 35,541 records; Model 2 was based on 32,011 records. Because of rounding, odds ratios with 1.0 as the lower or upper confidence limit may be statistically significant. A variable for missing data on income was included in the models; the odds ratios are not shown. | ||||||||
