Risk and benefit visualizations rely on data from individual clinical trials or meta-analyses.
When data is based on an individual clinical trial, we visualize particular efficacy or safety data by converting the % of study patients experiencing a benefit or risk into an absolute benefit/risk to 1,000 and 10,000 people. We are visualizing this data compared to placebo, except where stated, so the charts only show the treatment effect. We may look to include the benefit/risk from placebo and/or natural course of disease in future.
When the visualization is based on a meta-analysis, we will have converted either a number needed to treat (NNT) or an absolute risk reduction (ARR) into an absolute benefit/risk to 1,000 and 10,000 people. Many meta-analyses only provide relative risk data between two treatments, in which case we would not include this data in our visualization.
