What makes a fair comparison?

A direct trial is the strongest way to compare two treatments because the same study tests both. When no direct trial exists, we show each treatment’s evidence in separate columns and label that limit clearly.

Product comparisons use the current FDA labels. Form comparisons focus on practical differences between versions of the same medicine, such as a tablet and an injection.

For questions about using two compounds together, see the combination guides. They describe the evidence found for each pair and where it is missing.
