[1] After considering all indirect effects through mediators, direct effect of race on mortality was -0.115 with 95% CI(-0.713,0.526) in logisitic model and was -0.014(0.034,0.007). [2] 95% confidence interval is 0.025 and 0.975 percentiles of the distribution of statistics obtained by bootstrap with 1000 repetitions.
