Figure 2.

Forest plot from meta-analysis of standardized mean difference in circulating high sensitivity C-reactive protein for patients with CHF randomized to fish oil or placebo. The effect size of each study is proportional to the statistical weight. The diamond indicates the overall summary estimate for the analysis; the width of the diamond represents the 95% CI. CHF, chronic heart failure; hsCRP, high sensitivity C reactive protein; SMD, standardized mean difference; CI, confidence interval.
