Figure 2. — Contour Plots for the Meta-Analysis of the Association Between Proton Pump Inhibitors and the Six-Month Cumulative Incidence of Hospitalization for Community-Acquired Pneumonia in a Restricted Cohort of New Users of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

Notes: The top panel gives the meta-analytic summary estimate. The second, third, and fourth panels show contours for the point estimate, p-value, and I² statistic, indicating how each would change with the addition of an additional study, indexed by the size of the odds ratio (x-axis) and the standard error (y-axis) for the new study.
