A forest plot displays odds ratios and 95% confidence intervals for individual studies, with an overall pooled estimate, comparing intensive antihypertensive therapy to standard care. Translucent teal heterogeneity bands overlay the plot, extending across the full chart height for each study’s confidence interval to visualize between-study variability. The code uses D3 v6 with SVG rendering, a log scale for the x-axis, and data loaded from a remote JSON file. Study-level points are sized by sample size using a linear scale.
