Important disclaimer

The TTi website aims to deepen discussion about how we test whether treatments are worthwhile. We welcome discussion of the issues (described in the book) and examples.

However, we don’t want to make rulings on particular treatments, but instead discuss the strengths and weakness of the evidence behind them.

So in postings please feel free to raise issues or questions about the process of testing treatments, but if you want to use a specific medical condition can we ask that you:

1. Provide a link to the research behind the statement, and
2. Tell us how you found the research.
