Forest Plot with Heterogeneity Bands
This forest plot visualizes a meta-analysis comparing intensive antihypertensive therapy to standard care, showing odds ratios and confidence intervals for each study. Translucent heterogeneity bands behind the study markers reveal the range of effects across trials, with square marker size scaled by sample size. The visualization loads data from a JSON file and renders it as SVG using D3 v6, employing logarithmic scaling for odds ratios and d3.scalePoint for study positioning.
AI-generated descriptionHeterogeneity bands augment classic forest plots to provide a better visualization of heterogeneity between studies.
This project was submitted to the Wonderful Wednesdays challenge hosted by PSI and reviewed by statisticians in the organization.
