Myocardial infarction standardized incidence rates, absolute rate difference and corresponding 95% confidence intervals in the HIV-infected and general populations in calendar period.

Standardization is based on the age and gender distribution of the HIV-infected population between 2000 and 2009. Abbreviations: cART, combination antiretroviral therapy; HIV, human immunodeficiency virus; CI, confidence interval; PY, person-years; IR, incidence rate. The absolute rate difference (shown with the 95% confidence interval) per 100 000 person-years was estimated as the difference in the age standardized incidence rate between HIV–infected individuals and the general population. For each gender, the relative excess incidence rate in each calendar period was obtained dividing the absolute rate difference by the incidence rate in the general population. * P values for the relative excess incidence rates were obtained by Poisson regression by comparison between men and women in each calendar period.
