Abbreviation: CI Confidence Interval, exp exponent, HR Hazard Ratio, LCL Lower confidence limit, Log_e Natural logarithm, MA Mexican-American, NHANES National Health and Nutrition Examination Surveys, NHB Non-Hispanic Black, NHW Non-Hispanic White, PIR Poverty Income Ratio, SE Standard error, UCL Upper confidence limit
^aValues are the natural log of hazard ratios (HR) and 95 % CI with p-values, taking into account unequal probability of selection or sampling weights. Statistical significance is inferred from a 95 % CI not crossing the value of zero
^bModel 8 was Model 7 (Table 4) further adjusted for 3 health-related factors (co-morbidity, allostatic load and self-rated health). Note that the point estimate of the HR can be computed as exp(β) where β = Log_e(HR). The 95 % CI for the HR is computed as exp^{(β±1.96*SE(β))}, whereby SE(β) = (UCL_β -LCL_β)/3.92
