Poisson regression analysis for early mortality (within 30 days) prediction by demographic characteristics and clinical presentations.a,b

aThe data are presented as n (%) unless otherwise stated.bOnly mortality cases are included for analysis.cUnadjusted risk ratios and 95% confidence intervals for clinically relevant variables.dResults of stepwise selection for a fitted Poisson Regression model (Goodness-of-fit, Chi square = 9.55, p = 0.008). Variables were included in the final model for pTB, tuberculosis; MDR, multi-drug resistance; RR, risk ratio; CI, confidence interval.
