Figure 2 Odds ratio plots (logarithmic scale) for total mortality according to whether assigned to antiplatetet therapy or control. The center of each line represents the OR for the individual trials and subgroups with the ends of the horizontal line representing the 95% CIs. The solid line represents an OR of 1; to the left of the line (OR < 1) favors antiplatelet therapy, and to the right of the line (OR > 1) favors control or placebo. The broken line and the center of the box represent the pooled OR, and the ends of the horizontal line represent the pooled 95% CI. CI = confidence interval; OR = odds ratio.
