Model 1: Univariate.
Model 2: Multivariate - gender + Race/Ethnicity/SES + demographics + clinical + comorbidities (use individual variables).
aHR = Adjusted Hazard Ratio; 95%CI = 95% Confidence Interval.
None of the models included interaction terms. There are no significant interactions between gender and race, ethnicity, and NSES respectively in model 5. Race abbreviations are as follows: NA=Native American, PI=Pacific Islander, AIP = Asian Indian or Pakistani; NSES: Neighborhood Socioeconomic Status (living below poverty line); Lowest (≥20%); Middle-Low (≥10% and <20%); Middle-High (≥5% and <10%); Highest (<5%).
