  1. Confidence intervals in parentheses. * p < 0.05, ~ p < 0.10. Model included health status (BMI, ADLs, comorbidities), age, and gender. Income quintiles vary by year and were included in the model but excluded from t created using Household Income Quintiles data from Urban Institute & Brooking Institution Tax Policy Center [10]. Upper limits for quintiles are as follows: 2008: Q1: $20.712, Q2: $39,000, Q3: $62,725, Q4: $100,240, Q5: >$100,240. 2010: Q1: $20,000, Q2: $38,000, Q3: $61,500, Q4: $100,029, Q5: >$100,029. 2012: Q1: $20,599, Q2: $39,764, Q3: $64,582, Q4: $104,096, Q5: >$104,096. 2014: Q1: $21,432, Q2: $41,186, Q3: $68,212, Q4: $112,262, Q5: >$112,262
