Association Between MIs and ABC Exposure Based on Clinical Trials With ABC Randomization and With ≥48 Weeks of Postexposure Follow-up

	No.	ART Exposure, Person-Years	Events, No.	Proportion of Events (95% CI)	Exposure-Adjusted IRa (95% CI)	RRa (95% CI)
Exposed	2966	3999	6	0.20 (0.07–0.44)	1.50 (0.67–3.34)	0.69 (0.24–1.98)
Unexposed	2993	3670	8	0.27 (0.12–0.53)	2.18 (1.09–4.40)

^aPoisson regression model was fitted to estimate IRs and RRs of MIs and cardiovascular events.

Abbreviations: ABC, abacavir; ART, antiretroviral therapy; CI, confidence interval; IR, incidence rate; MI, myocardial infarction; RR, relative rate.
