An Analysis of Results from 18,317 Patients Pooled from 5

An analysis of results from 18,317 patients pooled from 5 large randomized controlled trials on drug X revealed the following relative rates (RR) for drug X compared to the control:
RR of cardiovascular mortality = 0.90 (95% confidence interval [CI], 0.73-1.38)
RR of heart failure = 2.09 (95% CI, 1.52-2.88)
RR of myocardial infarction = 1.18 (95% CI, 0.86-1.31)
Based on the results of this meta-analysis, there is a statistically significant increase in which of the following events among patients taking drug X?

A) Cardiovascular mortality and myocardial infarction
B) Cardiovascular mortality only
C) Heart failure and myocardial infarction
D) Heart failure only
E) Myocardial infarction only
