Enhancing forest plots improves the clarity and effectiveness of meta-analysis visualizations. Forest plots display the effect sizes of individual studies and the overall pooled estimate, but can be difficult to interpret without clear labeling and design. To enhance readability, use consistent color schemes to differentiate studies, significance markers, and confidence intervals. Ensure axis labels are clear and include both point estimates and confidence intervals for transparency.
Group studies by subcategories, such as study type or population, to facilitate comparison. Add a central line of no effect (e.g., 0 for differences or 1 for ratios) to highlight significant findings. Include annotations or tooltips for additional context, such as study design or sample size. Consider interactive features that allow users to explore data in more detail. Adjust the plot size and layout to avoid clutter, especially when dealing with numerous studies. By refining these elements, enhanced forest plots provide clearer, more informative visualizations for interpreting meta-analysis results.
