a
For all continuous variables, standard deviations are provided in parenthesis next to the mean.
b
P-values test for NHWhite vs. NHBlack differences. For binary variables P-values are based on logistic regression and for continuous variables P-values are based on OLS regression. P- values for concentrated disadvantage quintiles are based on ordinal logit models and P-values for network members and number of comorbidities are based on Poisson regression.
