	Estimate	95% CI
Risks in ITART Study population (n = 395)
Observed risk^a	0.095	0.064, 0.126
Estimated (modeled) risk under observed implementation fidelity to the CD4-stratified ART initiation strategy^b	0.120	0.082, 0.157
Estimated risk under complete implementation fidelity to the CD4-stratified ART initiation strategy^b	0.078	0.030, 0.128
Contrast measures
Estimated risk difference in mortality between observed and complete implementation fidelity^b	−0.042	−0.081, −0.003
